WARNINGS

The use of the Multiple Integrated Laser Engagement System (MILES) may induce violent evasive maneuvers in response to “near miss” signals. Therefore, troop leaders must enforce appropriate safety regulations, especially around vehicles and equipment. They must also ensure that the following safety procedures are observed by all personnel.

BLANK AMMUNITION

MILES requires the use of blank ammunition for all weapons. Never fire blanks at personnel or equipment at close range. Enforce established blank firing safety precautions.

LIFTING

The MILES transit cases have a four person lifting requirement. Failure to use a sufficient number of personnel during movement of a transit case could result in their injury.

LASER WARNING

The MILES IWS non-visible laser have been certified Class 3R eye safe, nevertheless, some precautions are needed:

• NEVER fire the laser transmitter at personnel or look at a MILES laser closer than 10 meters.

• NEVER fire a laser transmitter at personnel or look at a MILES laser closer than 50 meters using magnifying optics such as binoculars, telescopes, or periscopes.

The MILES IWS visible alignment laser is classified ANSI Class 2. Personnel should never stare at the alignment laser beam or intentionally aim the beam into another person's eyes.

SAFETY SUMMARY

• The use of the Multiple Integrated Laser Engagement System (MILES) may induce violent evasive maneuvers in response to “near miss” signals. Therefore, troop leaders must enforce appropriate safety regulations, especially around vehicles and equipment. They must also ensure that the following safety procedures are observed by all personnel.

• MILES requires the use of blank ammunition for all weapons. Never fire blanks at personnel or equipment at close range. Enforce established blank firing safety precautions.

• Do not load MILES-equipped weapons with live ammunition or the wrong blank ammunition. IMPROPER AMMUNITION may cause FATAL INJURIES. Refer to associated weapon’s technical manual for information on the use of blank ammunition.

• Ensure that the weapon has correct Blank Fire Adapter (BFA) and it is attached to the weapon correctly. Failure to install the blank adapter when firing blank ammunition could result in serious injury or death.

• MILES equipment transit cases have multiple person lift requirement. Restrictions are stated on the transit case. Failure to use sufficient personnel could result in injury during transit case movement or retrieval.

• Any batteries or otherwise hazardous materials replaced as routine maintenance should be disposed in accordance with local procedures and material manufacturer’s instructions.

• Always replace both HCU batteries at the same time from the same manufacturer. Never use rechargeable batteries or mix non-rechargeable and rechargeable batteries as a replacement set.

LASER WARNING

The MILES IWS System uses pulsed infrared laser beam to simulate bullets. The MILES IWS non-visible laser transmitters have been certified Class 3R eye safe, nevertheless, certain precautions are needed:

• NEVER fire the laser transmitter at personnel or look at a MILES laser closer than 10 meters.

• NEVER fire a laser transmitter at personnel or look at a MILES laser closer than 50 meters using magnifying optics such as binoculars, telescopes, or periscopes.

• A train-the-trainer or user-level course in laser/optical radiation hazards is available from the USACHPPM LORP

The MILES IWS visible alignment laser is classified ANSI Class 2. Personnel should never stare at the alignment laser beam or intentionally aim the beam into another person's eyes.

TM 23-6920-706-10

CAUTIONS

• Any batteries or otherwise hazardous materials replaced as routine maintenance should be disposed of in accordance with local procedures.

• If an item that is designated for long-term storage exceeds the item’s battery manufacturer’s long-term storage limit, remove the batteries from the item.

• Ensure battery caps are securely closed during storage or operations.

• Use care when starting SAT screws to not cross threads. DO NOT use any tools to tighten screws until directed.

CHAPTER 1 INTRODUCTION

SECTION I. GENERAL INFORMATION

1.1 SCOPE.

This manual describes how to install, operate, and perform user maintenance of the following components of the MILES IWS System:

a. Manworn (H-harness and head halo).

b. Small Arms Transmitter (SAT).

c. Ancillary items, such as dry fire trigger.

For operation of the Training Data Transfer Device (TDTD) System, please refer to the separate documentation, “Operator Manual, Multiple Integrated Laser Engagement System (MILES), Individual Weapon System (IWS), Training Data Transfer Device (TDTD), 23-6920-707-10.”

NOTE

Controller devices come in several forms; there are controller devices that produce laser outputs packaged as pistol shapes or keyfobs. The Universal Controller Device (UCD), or “Blue Gun”, provides similar funtions as the MILES 2000 Controller Device/Training Data Transfer Data (CD/TDTD). The Micro Controller Device (MCD), or “keyfob”, only output MILES laser codes. The TDTD with opto ports must be used to load HCU event data. The MILES IWS TDTD is the only device capable of downloading data from the IWS HCU and uploading data to the MILES After-Action Review System (MARS).

1.2 MAINTENANCE FORMS AND RECORDS.

Department of the Army forms and procedures used for equipment maintenance will be those described by DA PAM 738-750, The Army Maintenance Management System (TAMMS).

1.3 QUALITY DEFICIENCY REPORT (QRD).

If the MILES Individual Weapon System (IWS) equipment needs improvement, send us a QRD, form SF 368. Explain what the issue is with the design or performance. Put it on a Quality Deficiency Report, form SF 368. Mail the report to the Commander, Program Executive Office for Simulation, Training, and Instrumentation (PEO STRI), ATTN: SFAE-STRI-PS-Q (MILES IWS), 12350 Research Parkway, Orlando, FL 32826-3276. A notice of receipt will be sent. A notification of status will be sent shortly thereafter.

1.4 CORROSION PREVENTION AND CONTROL.

a. Corrosion prevention and control of army material is a concern. It is important that any corrosion problems with this item be reported so the problem can be corrected and improvements can be made to prevent the problem in the future.

TM 23-6920-706-10

1-2

b. While corrosion is typically associated with rusting of metals, it can also include deterioration of other materials such as rubber and plastic. Unusual cracking, softening, swelling or breaking of these materials may be a corrosion problem.

c. If a corrosion problem is identified, it can be reported using QDR form SF-368. Use of key words such as “corrosion,” “rust,” “deterioration,” or “cracking” will assure the information is identified as a corrosion prevention and control problem.

d. Mail the report to the Commander, Program Executive Office for Simulation, Training, and Instrumentation (PEO STRI), ATTN: SFAE-STRI-PS-Q (MILES IWS), 12350 Research Parkway, Orlando, FL 32826-3276.

SECTION II. EQUIPMENT DESCRIPTION

1.8 EQUIPMENT CHARACTERISTICS, CAPABILITIES, AND FEATURES.

1.8.1 Equipment Background and General Characteristics. The family of the basic MILES systems and products was developed in the early 1980s using technology and designs that were available at that time. MILES equipment provides for enhanced force-on-force simulation and simulation of armor and anti-armor devices.

The MILES Individual Weapon System (IWS) is an enhanced system developed to replace the existing U.S. Army direct fire ground based basic man-worn MILES or MILES 2000 devices employed in the laser-based enhanced Tactical Engagement Simulation (TES) training devices. All enhanced MILES systems and devices like those that are part of the MILES IWS, are designed to be downwardly operationally compatible with the earlier basic MILES and MILES 2000 training devices.

1.8.2 Capabilities and Features.

a. The following are the highlights of the enhanced MILES IWS family of training devices:

(1) Consists of a family of laser-based training devices appended to foot soldiers and individual weapons.

(2) Has a modular design with the flexibility to permit upgrading of the training system to accommodate product improvements.

(3) Simulates each specified weapon and ammunition effect on a MILES equipped system and has the capability for use in darkness within the capabilities of the weapons with which it is being used.

(4) Interfaces and is compatible with legacy MILES training devices by way of the specified laser communication channel through the atmosphere in accordance with (IAW) PMT-90-S002.

(5) Provides an external RS-232 serial interface to enable, send, and receive real-time data from player units/radios necessary to interface to the instrumented Combat Training Centers (CTCs) or Initial Homestation Instrumentation Training Systems (IHITS).

(6) As the result of a blank fire in an engagement, transmits messages that contain a unique PID code and the weapon and ammunition code IAW PMT-90-S002.

(7) Engagement results are indicated to the target and attacker using visual and audible cues.

(8) Stores engagement data in electronic media for retrieval and use in After Action Reviews (AARs) at instrumented ranges or Miles After Action Review system (MARS).

1.9 DESCRIPTION OF MILES IWS SYSTEM.

1.9.1 Major Components of MILES IWS System.

a. The major components of the MILES IWS Training System are:

(1) MILES Individual Weapon System (IWS) equipment comprising:

(a) Manworn

- H-harness (torso) - Halo (headpiece)

(b) Small Arms Transmitter (SAT)

(c) Dry Fire Trigger (DFT). This is an optional device used in place of blank fire ammunition.

(2) Training Data Transfer Device (TDTD) System comprising:

(a) A MILES After Action Review System (MARS) software package

(b) PC laptop with a Computer Optical Port (COP) interface

b. The TDTD system is discussed in PEO-STRI Manual, 23-6920-707-10.

c. Controller devices and their functions are discussed in separately fielded manuals available from PEO-STRI.

1.9.2 MILES IWS Components.

1.9.2.1 H-harness and Halo. The H-harness is worn over the operative's clothing and the halo is worn over a helmet or cap. It consists of an H-harness shown in Figure 1-1, and a halo shown in Figure 1-2 with the following components:

a. Twelve (12) Laser Detector modules are combined in three (3) detector assemblies or “looms” receive MILES coded laser beam pulses from laser transmitters. The H-harness has eight (four each on front and back) distributed detectors, and the halo has four detectors (two forward and two aft).

b. The Harness Control Unit (HCU) is located in a pouch about waist belt high on the front right side of the H-harness. It provides decoding, hit outcome determination, data storage, user interface (LCD display and buttons), and control mode for maintenance purposes. The harness control unit stores the events data and provides the user a menu of features. It sends Infrared (IR) data from the H-harness Comms module, located chest high, to the SAT. The HCU may receive IR data from a controller device or optical data from/to TDTD. The MILES IWS HCU has a preset Player ID (PID) programmed into it. The PID is used for shooter ID as part of event reporting and analysis. The H-harness PID is retrievable from the display. In addition, the HCU contains the H-harness battery compartment secured by a user removable cap. The HCU uses two lithium 2/3A type (3 volt) batteries. When batteries are installed or when directed to replace, the HCU Built-In-Test (BIT) routine is executed.

TM 23-6920-706-10

1-7

c. The H-harness communication link is contained in the “Comms Module” on the upper left front of the H-harness. The communications link between the SAT and H-harness is Infrared (IR) transmission. Using IR linking, the SAT adopts the Player Identification (PID) and ammo type of the shooter, attributing any (laser) shots fired to the shooter.

d. An audio speaker is located high on the right rear of the H-harness. It is used to provide audio cues to indicate that an action has occurred such as a laser message being received with results of the hit. This box also has a LED that illuminates when the H-harness recognizes a “hit.” This indication may be seen by following personnel.

e. The H-harness-halo inductive loop is employed to transfer information from the helmet halo detectors to the H-harness HCU for processing. An internal long-life battery (1/2 AA, 3.6V, lithium) contained in a halo amplifier module powers the halo.

f. With an “awaken” halo and twelve inches from the H-harness inductive loops, pressing the Halo BIT button commands a Halo BIT and tests the battery voltage. The BIT result is a read-out on the HCU display.

g. Both the halo and H-harness have attachment mechanisms and adjustment straps or clips to fit over or around soldier equipment such as flak jackets and night vision equipment.

1.9.2.2 The Small Arms Transmitter (SAT). The SAT (shown in Figure 1-3) is adapted for a specific weapon through factory set lasers (visible and invisible). The alignment knobs accomplish laser beam alignment. The laser power is factory adjusted to represent the specific weapon type and simulate its firing capabilities. It is powered by a 1/2 AA, 3.6V, lithium battery that can be removed by the user.

The SAT is attached to the barrel of the player’s weapon. When the flash/bang sensor detects a blank fire event, the SAT emits coded laser beam in accordance with PMT-90-S002. The laser beam contains data on shooter’s MILES Code (PID with ammo type) and the SAT LED will flash. The target’s H-harness records the time and date of the shot if, time is synced, the data coded in the laser beam, and the outcome of the casualty assessment.

Figure 1-3. Small Arms Transmitter.

The clamp and screws attach the SAT to a specific weapon.

Modified M240 SATs (P/N: 303650-1) are mounted on a Mounting Bracket with a Picatinny Rail that is used to attach the SAT to the barrel of a player’s weapon. The modified SAT uses a Picatinny clamp to attach the SAT onto the Picatinny Rail Mount or specific small arms weapons fitted with Picatinny rails,

as shown in Figure 1-4. The multi-weapon mounting bracket, weighing approximately 10 ounces, secures the SAT to a variety of weapons that are not fitted with Picatinny rails. The multi-weapon mounting bracket can accommodate various size barrels. The feature of the Picatinny clamp and the multi-weapon mounting bracket streamline the installation of the SAT onto most light weapons in less than 1 minute.

1.9.3 Ancillary Items. The transit cases contain specific color-coded ((gold (20 inch-pounds) for M110, M240 SATs, green (85 inch-pound) for all SATs except M110 and M24, or red (60 inch-pound)) torque wrenches for M24 SAT. They are provided for SAT installation and removal from a weapon. A soldier operator may also be provided a Dry Fire Trigger (DFT) shown in Figure 1-5, so that the weapon may be operated without using blank ammo. The DFT is further discussed in Chapter 2, section 2.17.4. It is powered by an internal 1/2 AA, 3.6V, lithium battery.

The transit case contains H-harnesses, the helmet halos, SATs, any required SAT installation tools, a copy of the operator’s manual, and quick reference cards. The total number of IWS kits may vary according to the type of SAT packed. There are three transit case interior configurations for the six variants of SATs. The transit case interiors contain cut-outs specifically shaped to hold the individual components. Representative transit case interior layouts for the M16A2/M4, M24; M240, M249, and M107; and M2 are shown in Figure 1-7. This figure also shows a sniper case containing various sniper weapon SATs (such as M107 and M110). Missing components can be easily identified. When the equipment is not in use, it is recommended that the transit cases and accompanying form parts be retained for safe shipment and storage of the equipment. Tables 1-3 through 1-8 provide transit case content for the each of the IWS kits. The number of IWS kits in a transit case is dependent on the number of weapon SATs and the weight allowance.

SECTION III. THEORY OF OPERATIONS

1.11 MILES IWS SYSTEM OPERATION OVERVIEW.

The MILES IWS System is a laser-based system, which simulates the effects of small arms live fire in field exercises. It gives the soldier the realism of being able to accurately use a weapon in a two-sided force-on-force exercise. At the same time, it provides feedback on the effectiveness of the soldier’s own fire position, weapon skills, and use of ground cover during combat training exercises.

The MILES IWS equipment allows the training of troops in the field by providing a high level of realism, enforcing correct procedures and yielding outcomes that would be expected in actual operation. Training results range from procedural use of equipment and field craft to tactical aspects of an exercise obtained during the exercise or an after action review.

The MILES IWS equipment can be used as stand-alone equipment for dismounted troops or in conjunction with the optional MILES-equipped vehicles, surrogate weapons, or crew-served weapons.

1.11.1 Basic Principles of Operation. During combat exercises, weapons fitted with Small Arms Transmitters (SATs) and Blank Fire Adapters (BFAs) are made to fire blank ammunition in accordance with normal weapon firing procedure. The flash from the weapon’s muzzle and shock of the weapon’s bolt action or firing is sensed by the SAT to fire MILES coded laser beams. Alternatively, weapons can be fitted with a dry fire trigger (DFT) attached to the SAT. The DFT causes the SAT to fire MILES coded laser beams when the fire button is depressed. The laser beam simulates weapon’s capabilities including range, accuracy, and destructive capability.

The H-harness and helmet halo are fitted with detector modules. Hits and near-misses from the MILES coded laser beams fired by SATs are recorded on the H-harness detectors which generate electrical signals that are fed to the H-harness HCU for processing. Hits are evaluated by the H-harness to determine whether a ‘kill’ has resulted.

Some core advantages of the MILES IWS equipment include:

a. Ease of installation, alignment, and set-up in a minimal amount of time.

b. Lightweight and robust equipment compared to previous generation MILES.

c. Realistic engagement range.

d. Individual weapons are fired using normal procedures. No weapon modifications are needed to use MILES IWS equipment.

1.11.2 Extension of the MILES IWS System to I-HITS, HITS, and MCTC. The MILES IWS system equipment can be optionally extended to be used with the Initial-Homestation Instrumentation Training System (I-HITS), Homestation Instrumentation Training System (HITS), or Maneuver Combat Training Center (MCTC) Instrumentation. The instrumentation employs GPS satellite technology and radio links to achieve real time reporting and recording of events during the exercises. By using remotely located instrumentation computer screen and keyboard, exercise commanders can take action in real time while exercises are in progress. The events are recorded by a remotely located Exercise Control Computer (EXCON) and the recorded events can be played back or reports may be printed for after action reviews.

TM 23-6920-706-10

1-21/(1-22 Blank)

1.11.3 Limitations.

The MILES IWS system equipment supplements the soldier’s operational equipment. Training device limitations include the following:

• The weight and cube of IWS components are added to the soldier’s operational equipment so soldier’s overall weight carried is impacted.

• IWS components are battery powered; loss of power will prevent a soldier to simulate a shot or “hit.”

• IWS employs Probability of Kill (Pk) tables to account for hits and kills. Pk tables are statistical and do not duplicate real situations.

• IWS H-harness and halo must communicate to record halo events.

• IWS H-harness and SAT must communicate and associate to shoot SAT laser beam. Lack of association will prevent shots.

• With IWS use, a soldier can not “shoot” oneself.

• IWS equipment employs audio-visual cues to alert the soldier of events (LEDs, displays, and speaker tones). It can not duplicate actual sounds and sights.

• Laser beam does not duplicate the actual ballistics of a soldier’s weapon.

• IWS dry fire mode can not account for soldier’s ammunition limits.

• The IWS dry fire trigger employs a button switch to activate and fire the SAT.

CHAPTER 2 OPERATING INSTRUCTIONS

SECTION I. H-HARNESS INSTALLATION AND OPERATING INSTRUCTIONS

2.1 H-HARNESS/HALO INTRODUCTION.

This section describes the operation of the IWS system. The purpose of the H-harness and halo are to provide detectors and electronics necessary to receive MILES coded laser messages, process and display the results, and store and download events information for use later in event reviews.

The H-harness and the helmet halo have been shown in Figures 1-1 and 1-2. They have laser detectors to receive MILES coded laser beams shot by a Small Arms Transmitter (SAT) shown in Figure 1-3. The IWS employs two techniques to handle components communications without restrictive wiring. One is an inductive link between the halo and H-harness, and the other is an IR link between the H-harness and the closest SAT.

The H-harness, worn over the soldier’s clothing/webbing to make laser detectors visible, adds vulnerability to the players in the field. This vulnerability involves the reception of threats and evaluation of the effect of the threat (‘kill’ or ‘near miss’) onto the soldier.

The harness control unit (HCU) is the central electronics hub for the player. It records the “killed” or “alive” status of the player, which will disable or enable the weapon systems (transmitters) associated with the player. The HCU provides display and command functions (buttons) for the player. The HCU also houses the battery compartment to power the H-harness.

2.1.1 Features of the IWS H-harness and Halo.

a. The following are the highlights of the IWS H-harness and halo:

(1) Eight detector modules combined in two assembly loops on the H-harness (front and back) and the four detectors in one assembly loop on the halo. These detectors provide 360º coverage of the body.

(2) Halo to H-harness inductive coupling between H-harness and halo and/or surrogate weapons to eliminate wires.

(3) Designed for minimum fabric area and use of current combat equipment such as night vision equipment.

(4) The H-harness is powered by two 2/3A 3V lithium batteries. These batteries are easily replaceable and the power capability is expected to last for an extended period such as an entire exercise. They may be replaced by warehouse personnel or by the user. The halo is powered by a single ½ AA 3.6V lithium battery. This battery is replaceable in the Life Cycle Contractor Support (LCCS) support shop with expected power duration of over a year. The power saving modes employed in the H-harness and halo extend battery life.

(5) Lethality assessments: Near Miss, Hit, Alive, and Killed provided.

(6) Audible alerts and sounds provided for near miss and kill.

TM 23-6920-706-10

2-2

(7) HCU may store up to a maximum of 498 events. Stored events data downloaded by TDTD.

(8) Selective Probability of Kill (Pk) tables are available for individuals. Programmable Pk tables are provided using the TDTD system.

(9) Internal real-time clock time tags events.

(10) Status and data query provided to the soldier by the HCU display.

(11) Player ID is factory programmed or can be field reprogrammable by the TDTD system or a controller device.

(12) BIT is performed in under a minute.

(13) Use of optical interface on the HCU to the Computer Optical Port (COP) also called TDTD to allow events downloading.

(14) RS-232 interface to a player unit for real-time data collection and processing at Combat Training Centers (CTCs) or other instrumentation systems like IHITS.

2.2 HOW THE H-HARNESS FUNCTIONS.

2.2.1 H-harness Operation – General. The laser detector modules present on the IWS (H-harness and halo) receive the MILES coded infrared laser beam from the transmitters (SAT and controller device); convert this to electrical pulses; and pass these to the Harness Control Unit (HCU) for processing. A speaker mounted in a module on the back of the H-harness inform the user when he has been hit or had a near miss from a SAT laser beam. Additionally a LED in the module will inform others that this player may have been hit.

All data associated with the player is stored in the HCU. An optical port on the front of the HCU is used to interface with the Computer Optical Port (COP) connected to the TDTD personal computer for event data transfer and set-up commands. Events data extracted from the H-harness are used for MILES After Action Review System (MARS). A wireless IR link between the H-harness and the SAT mounted on the player’s weapon provide status, control, and event information between the H-harness and the SAT. This H-harness – SAT link also ensures that the SAT is fired by a “live” H-harness as an “anti-cheat” feature for the MILES IWS system. The halo and H-harness communicate using inductive loop.

2.2.2 Laser Codes Decoded by H-harness. The H-harness decodes the MILES laser codes fired by the SAT and Controller Device in accordance with PMT-90-S002 MILES Communication Code (MCC) Standard so the MILES IWS can be used with other generations of MILES equipment.

2.2.3 H-harness Probability of Kill (Pk) Tables. The H-harness is configured for the individual soldier Pk as defined in the PMT-90-S002 MILES Communications Code (MCC) Standard. Based on the Pk tables programmed into the H-harness, the H-harness determines the effect of the received laser shots from SATs as “kill, hit or near miss.” The probability of killing a H-harness is different for each type of attacking weapon. Each laser shot fired by the SAT contains four kill words of MILES Code 27 (Small Arms) or 24 (Heavy MG), and 128 near miss words of MILES Code 29.

a. Body Armor Setting Selection: The IWS is not affected by the application of body armor. The use of Body Armor provides the Probability of kill (Pk) to be reduced to 50 percent for MILES Code 27 (Small Arms) detections.

TM 23-6920-706-10

2-3

b. The H-harness will record a near miss if it receives the near miss code irrespective of the body armor settings. In the SAT laser beam profile, the larger number of near-miss codes fired surround the weapon’s code. The H-harness determines whether the laser shot from the SAT was accurate enough to cause a ‘kill’ or whether a near miss occurred.

2.2.4 H-harness to Weapon Link. The H-harness to weapon (transmitter) link is achieved via the wireless IR. IR transmitters, located on the left front shoulder of the H-harness, provide wireless communication between the H-harness and the SAT associated with the H-harness. The rear of the SAT needs to be generally positioned beyond 10 inches from the H-harness’ Comms Module and upper left front detector (clear visible line of sight is the key). This will activate weapon IR link between the SAT and the H-harness. Association (ownership) of a SAT by the H-harness is achieved over the H-harness-SAT wireless IR link. The ammo type and player ID (PID) of the H-harness is transferred to the SAT and sent out with every shot fired by the SAT so that the shooter can be identified.

2.2.5 Anti-Cheat Features.

a. The H-harness and the SAT have the following safeguards (implemented over the H-harness – SAT IR link) to prevent a player from “cheating” during the exercises.

(1) A “killed” soldier cannot fire their own weapon (SAT).

(2) If the H-harness batteries are removed, the H-harness will power down. Except at battery low condition, upon re-insertion of the batteries the H-harness will display a cheat event in the log.

(3) Once there is a low battery indication for HCU, there is a three (3) minute period to replace the batteries to avoid the “cheat kill.”

(4) A back indication LED positioned in the rear of the H-harness provides visual “kill” indication to people following the soldier.

(5) The continuous KILL tone will sound for 5 minutes unless either a controller “resets” or “resurrects” the HCU, or the operator gets the SAT disabled and pushes any HCU button. If the SAT is disabled then the continuous KILL tone will last 30 seconds without pushing a button.

2.2.6 Halo-to-H-harness Inductive Link. The halo amplifier module has a circuit to allow halo-to-H-harness communication using inductive loops, thereby avoiding hard wire interconnections. The information communicated includes reception of laser codes by the halo to the HCU and a halo battery status indication. To conserve battery power, the halo amplifier has a “sleep mode” using a motion-sensing switch. When activated, the halo amplifier remains operational for approximately six minutes, after which it returns to “sleep mode.”

A pushbutton on the halo processor module shown in Figure 1-2 is used to send the halo battery status to the HCU. The request and response in text is depicted on the H-harness HCU display.

2.2.7 Serial Comms (RS232). Serial communication takes place between the HCU of the H-harness and a separate player unit using the RS232 serial communications protocol.

2.3.1 LED and Audio/Sound Indications. The IWS HCU provides LED and audible tones and speech to alert the user as to his or her system status. An audio replay speaker is also located at the back of the H-harness that provides audio playback of sounds and voices through an acoustic speaker. Weapons hit/near-miss events sounds are played. The circuitry to generate the enunciated sound is internal to the HCU module. These tones and sounds provide context to the soldiers.

a. Kill = Text “Kill” and Red LED on HCU LED and back LED.

b. Near Miss = Text “N Miss” for Near Miss and Green LED on HCU and 2 beeps.

c. Hit = Explosion Sound, Text “Hit.”

d. Reset or resurrect by controller = Audio “Reset” or “Resurrected” and steady Green LED.

e. Low battery = “LOW BATTERY” text or * with message in HCU display for the HCU.

f. Cheat Kill = HCU display text “Kill” and Red LED on HCU and back. “Cheat kill” text will be displayed in the Events submenu.

g. Kill = continuous tone until “reset” by controller or pushing a HCU button after the SAT has been disabled to acknowledge the disassociation. The continuous tone will last approximately 5 minutes with no SAT disable. If the SAT is disabled, the continuous tone will last 30 seconds or shorter if the operator pushes a HCU button.

h. SAT Enable/Disable = 1 beep by H-harness at enable and 2 beeps by H-harness at disable.

2.3.2 Rear H-harness Kill LED Indication. The rear H-harness kill indication LED mounted with the speaker box provides an indication of kill (Continuous Red LED).

2.3.3 Halo Controls and Indications. Figure 2-4 depicts the halo. It has one control button used to conduct a battery check of the halo shown in Figure 2-4. The HCU displays all indicators provided by the halo. The soldier may conduct a manual Halo Battery check by pressing the halo button. After pressing the halo button if there is no HCU display, ensure the halo is within 12 inches of H-harness inductive loops, move or shake the halo, wait 10 seconds, and press the halo button again.

(3) Ensure detectors and HCU display are wiped clean.

Refer to Chapter 3, Table 3-1 for recommended inspection frequency and paragraph 3.3.1 for more detailed inspection information.

2.4.1 Fitting H-Harness (includes HCU Batteries Installation). The H-harness is shown in Figure 2-5.

WARNING Always replace both HCU batteries at the same time from the same manufacturer. Never use rechargeable batteries or mix non-rechargeable and rechargeable batteries as a replacement set.

a. Insert batteries if required as shown Figure 2-2. This task may be a support contractor function. (1) Unscrew battery cap. (2) Clean cap threads with cloth or paper towel and inspect that threads are clean from dirt or

grit. (3) Replace the 2-2/3A lithium batteries. (4) Check polarity of battery with (+) side to the bottom. (5) Replace battery cap securely.

b. Fit H-harness over torso or webbing gear/Modular Lightweight Load-carrying Equipment (MOLLE) with the HCU forward.

c. Secure straps (4) in MOLLE attachment points or over pistol belt, etc. CAUTION

The HCU harness contains numerous wires. It is best operational practice to NOT bend the cable in two to secure the HCU. Secure the HCU so its cable is similar to that in Figure 2-5.

d. Adjust strap length if needed. NOTES

With a low battery indication (message or asterisk) displayed on the HCU, there is a 2-3 minute period to replace the batteries without a “cheat kill” event being recorded in the log.

If HCU Main software version 3.2.22 or higher is installed and the DCI Mode is set to 290065, the asterisk indicates the HCU is communicating to the Harness Instrumentation Overlay Player Unit, via the RS-232 serial cable.

TM 23-6920-706-10

2-8

If the batteries are removed for any reason other than low battery response or longer than 3 minutes, upon re-insertion the H-harness will display a cheat event in the log. The H-harness will need to be reset using the controller device. Halo needs to be within 12 inches of H-harness inductive loops and “awake” in order to respond to a battery status request. Halo is awaken by moving it.

Figure 2-5. H-harness.

2.4.2 Optional Harness Adapter. An optional instrumentation overlay kit or instrumentation harness adapter assembly may be coupled with the H-harness to provide instrumentation range communications and Global Positional System (GPS) position data so MILES IWS player event data is transmitted to the instrumentation range exercise control. The adapter harness assembly contains the Data Communications Interface (DCI) unit (also referred to as a Player Unit) antenna, GPS antenna, battery case, and associated cables.

a. The adapter harness assembly should have a charged battery that is not yet installed. Verify this by opening the two instrumentation compartments shown in Figure 2-6 to reveal the battery case pouch and Data Communications Interface (DCI) pouch. Ensure the battery is not installed in the pouch and therefore not connected. Ensure there is a DCI (Player Unit).

When HCU Main software version 3.2.22 or higher is installed and the DCI Mode is set to 290065, the following functions are available at the HCU.

• Casualty Card messages

• Room Illuminator messages.

2.7.1 Casualty Card Message

Casualty messages are displayed at the HCU when the instrumentation harness adapter assembly is connected to the H-harness. The Casualty Card Control Message (6D) enables and disables the Casualty Card display on the HCU. These control messages provide the HCU how many (1-16) lines of text to display in each category (Injury, Action, Medic, OC Code).

Casualty Card Data Message (6E) provides the text for the HCU to display. The current Player Unit software sends “YOU ARE DEAD” when the Harness is killed.

NOTE

The current HCU is limited to four lines of Injury text and no Action, Medic or OC Code text. PU software would need to be changed to send additional messages to the HCU.

When connected to a DCI that supports Casualty Cards a Casualty Report Menu option may appear during pre-defined conditions.

2.10 TIME SYNC.

NOTE

Controller devices will operate with the MILES IWS system, but are not fielded with the IWS system. If the instrumentation harness adapter assembly is connected to the IWS harness assembly, a time sync message is received from the instrumentation upon initialization at EXCON.

At the beginning of an exercise or after battery replacement, each IWS HCU should have its internal time clock synchronized. It is done to achieve a proper sequencing of events for later review.

Have the Controller perform a “Time Sync” on the IWS HCU using a Controller Device or equivalent. Aim at any detector and pull the trigger. A time stamp will appear in the display.

NOTE(S) Ensure that you use a Controller Device that has been time synchronized by another Controller Device. This ensures that all exercise units and Controller Devices have the same date and time.

If the time sync is performed by the IWS TDTD system (COP and MARS). Time and date are entered into the HCU. If the time sync is performed by another Controller Device then only the time is entered into the HCU.

If a DCI is connected to the Harness, Time Sync with the PU GPS will be automatic and will be seen at the “USER INFO/--:--:--“ MENU.

2.11 VIEW USER INFORMATION SUBMENU OPERATION.

When the “Press Enter to view user info” is displayed and the “Select/Enter” (↵) button is then pressed, the View User Info submenu commences. By pressing either of the (/) push buttons this submenu will cycle through its ten (10) elements of information in this informational submenu. The purpose of each feature is indicated in Table 2-2 ( is shown as + and is shown as -).

TM 23-6920-706-10

2-21

NOTE(S) Most categories of this submenu are programmed into the HCU during support contractor H-harness configuration actions using the HCU controller mode. The typical user will see the results of the action using the User Info Submenu. Support contractor configuration actions normally include time syncing using a Controller Device and selecting the Pk (default (flak jacket off), regular, or custom), PID code selection (even number for Bluefor and odd number for Opfor), RF/IR mode operation selection, and DCI mode on (for a DCI #) or none (off). A typical user has no need to use the controller mode function. An Observer Controller (OC) with a controller device may perform a pre-operational Time Sync.

SECTION II. SMALL ARMS TRANSMITTER (SAT) INSTALLATION AND OPERATING

INSTRUCTIONS

2.15 SAT INTRODUCTION.

This section describes the Small Arms Transmitter (SAT). The SAT is the laser transmitter unit for small weapon type simulation within the MILES IWS system.

The SAT, mounted on the barrel of a weapon, simulates the effect of a live round being fired from a weapon by emitting a pulse of coded laser beam. At time of firing, flash from the muzzle and the blank ignition event (bang) is detected and the coded laser beam is transmitted. The SAT may also be alternatively triggered into operation with a dry fire trigger with firing button switch.

a. The SAT has three basic functions:

(1) Firing of coded laser beams when required.

(2) Communicate with the H-harness via the IR link.

(3) Communicate with the TVS via the IR link (for association) and RF link.

WARNING

The SAT is a Class 3R laser product.

2.15.1 Weapons Simulated by SAT. The SAT simulates the firing characteristics and range of the following weapons to which it is fitted. (Refer to Table 2-6.)

2.15.2 Features of the SAT.

a. The following are the highlights/advantages of the enhanced MILES IWS SAT:

(1) SAT accurately replicates weapon performance.

(2) Once secured and aligned, SAT retains alignment until removed.

(3) To prevent “cheating,” SAT is automatically disabled if the player is “killed.”

(4) To prevent accidental firing, SAT requires both flash and bang to trigger laser fire.

(5) Visible indication LED indicates firing.

(6) Rapidly aligned using visible laser.

(7) Player ID embedded in the laser code to enhance AAR.

(8) Backward compatible with the existing MILES equipment.

(9) Dry fire mode supports operations, testing, and maintenance.

(10) Accommodates both optical sights and night vision devices.

(11) Easy to fit to a weapon.

2.16 HOW THE SAT FUNCTIONS.

2.16.1 SAT Operation – General. The SAT emits a coded laser beam pulse to simulate the effect of a live round being fired from a weapon. This allows simulation of small arms weapons and machine guns, allowing force-on-force engagements.

2.16.2 SAT Activation. In use, the SAT is clamped onto the barrel of a weapon using a weapon specific clamp and is activated to fire coded laser beams when blanks are fired by the weapon. An internal sensor in the SAT detects the shock “bang” of a blank cartridge and the flash sensor detects the flash generated from the blank fire explosion. Alternatively, the SAT can be activated to fire the coded laser beam by using the dry fire trigger.

2.16.3 MILES Laser Codes Shot by SAT. Upon activation, the SAT fires MILES laser codes in accordance with the PMT-90-S002 MILES Communication Code (MCC) Standard.

a. The MILES laser code fired by the SAT contains the following information:

(1) Weapon type (MILES definition)

(2) Ammunition type (MILES definition, as appropriate)

(3) Player Identification (of the associated H-harness)

TM 23-6920-706-10

2-31

b. Depending on the weapon simulated, each laser shot fired by SAT consists of 4 words of MILES code 24 or 27 followed by 128 words of Near Miss code 29. The H-harness laser detection system, which receives the laser shot, determines the outcome as kill, hit, or near miss.

2.16.4 SAT Interactions. The communications interactions of the SAT are shown in Figure 2-12.

Figure 2-12. SAT Interactions.

a. As shown in Figure 2-12, the SAT interacts:

(1) With player H-harness through IR for SAT-H-harness association, permission to fire, anti-cheat implementation.

(2) With the Dry Fire trigger with the IR link to send a signal from the dry fire trigger switch for activation.

(3) Sends MILES coded laser beam signal to targeted laser detectors.

(4) With the MAJiK for SAT alignment on the weapon by means of a visible laser that is activated by a H-harness HCU command.

(5) A SAT programmed with a IEEE MAC Address and serial number can be associated to a Tactical Vehicle System (TVS). The SAT is associated to a TVS through the IR link. After the SAT is associated to the TVS, the SAT communicates on the Personal Area Network (PAN) over the RF link.

2.17 SAT PHYSICAL DESCRIPTION.

The external case of the SAT is sealed to preserve the internal electronic components. All lenses are recessed to minimize any scratching of surfaces that may occur in the field. The battery compartment cap is knurled to be easily removed and replaced.

a. There are two exterior designs of SAT in which only the alignment knobs are different:

(1) Typical -1/-3 configurations, the laser alignment knobs are knurled and designed to be easily pulled opened and pushed close by hand without the need for any tools. (See Figure 2-13.) Knurled knob configurations of M249, M2, and M110 SATs were not fielded.

Modified M240 SATs (P/N: 303650-1) are mounted on a Mounting Bracket with a Picatinny Rail attached to the barrel of the player’s weapon. The modified SAT uses a Picatinny clamp to attach the SAT onto specific small arms weapons fitted with Picatinny rails, as shown in Figure 2-14.

Figure 2-14. Modified SAT with Picatinny Rail Mount.

2.17.1 IR/Visible Laser.

a. The IR laser fires the MILES coded laser beam generated by the SAT upon initiation. The alignment of SAT laser beam to the weapon sights are performed using the alignment paper targets. The process of aligning the SAT is similar to live fire “zeroing” practice.

b. The visible laser is co-aligned to the IR laser and shoots visible laser light which helps in alignment of the MILES coded IR laser beam. The visible laser beam and the IR laser beam move together as the alignment knobs on the SAT are rotated.

2.17.2 Flash Sensor and the “Bang” Microphone.

a. The flash sensor, situated adjacent the laser, detects the visible flash from the blank round fire.

b. The microphone unit is an internal sensor that detects the noise of a weapon firing.

2.17.2.1 Blank Fire Initiation. When used in the blank-fire mode, the SAT will fire the laser beam when it gets both the shock input and the flash sensor signals upon weapon firing a blank round.

2.17.3 Comms Port.

a. The extended area covered by a red lens towards the rear of the SAT is the comms port of the SAT and is used for providing the following functions:

Picatinny Rail

Mounting Bracket

Picatinny Clamp with captive screw

(1) Wireless IR link between the SAT and the H-harness and dry fire trigger (DFT).

(2) LED indication (red flashes to indicate association, firing of laser, etc.).

b. The communications port is located near the battery compartment on the rear side of the SAT.

c. Communication with the H-harness happens over the short range wireless IR link. The LED in the comms port indicates the various SAT actions. (See Table 2-5 in section 2.19 for “LED Responses of the SAT.”)

d. Communication with the TVS happens over the short range wireless IR link and RF link.

(1) SATs programmed with a IEEE MAC Address and serial number are associated to a TVS over a one-way IR link between the SAT and the TVS Crew Control Module (CCM).

(2) Once the association of the SAT to the vehicle TVS system is accomplished, the SAT communications between the associated TVS equipment is conducted by means of an RF link (Zigbee; IEEE 802.15.4), reference OUM 23-6920-708-10, Operator User’s Manual for I-MILES TVS.

2.17.4 Dry Fire Trigger. The dry fire trigger (DFT) assembly mounts to the top of the SAT and on closure of the switch sends an IR signal to the SAT. When shooting, the user needs to squeeze the trigger as shown in Figure 2-14.

Figure 2-14. Dry Fire Trigger Assembly (1265-01-542-4252).

a. Prior to installation, inspect the DFT for obvious physical damage. Return the unit if damaged.

Refer to Chapter 3, 3-1 for inspection frequency.

b. To attach the DFT:

(1) Find the recessed groove on the comms port side of the SAT and the ledge of the DFT interior as shown in Figure 2-15.

Fire Button

DFT SAT Attachment Assy

(2) Match recess and ledge and snap DFT fitting over SAT battery compartment as shown in Figure 2-15.

(3) Ensure SAT and DFT comms ports are not obstructed as shown in Figure 2-16. The DFT communicates with the SAT using the IR link.

Figure 2-16. DFT to SAT Attachment

c. To remove the DFT: From the recessed groove side of the SAT, pull the DFT fitting up to loosen and remove the DFT from the SAT.

2.17.5 Alignment Knobs. The two alignment knobs located on the front of the SAT allow the laser to be zeroed to the weapon sights. There are two types either Low profile or knurled knobs. The low profile knobs are turned by a coin or flat screwdriver or a flat edge object. The knurled knobs are rotated by hand without the need for any tools. When aligning via the knurled knobs the knob is engaged by “pulling.” To disengage or secure the knurled knob “push” the knob in.

2.18 SAT BATTERY.

The SAT uses one ½ AA sized lithium battery. This battery normally is replaced by a support contractor.

2.18.1 Low Battery Indication. The low battery indication begins when the battery remaining capacity is low. It is shown by the SAT LED light remaining on after an event.

2.18.2 Fitting the Battery. The battery compartment cap is knurled for easy opening and closing by hand. The battery cell is fitted as shown in the following steps (see Figure 2-13):

a. If SAT is associated with an H-harness, disassociate the SAT.

NOTE

If a SAT is associated and the SAT battery is removed, then it causes a “cheat kill” situation and the H-harness will need to be RESET.

b. Unscrew battery compartment cap.

c. Clean cap threads with cloth or paper towel and inspect that threads are clean from dirt or grit.

2.21 ALIGNMENT OF THE SAT.

a. The SAT is aligned to the weapon sights by using the Mirror Alignment Jig Kit (MAJiK) Assembly. The SAT must be aligned each time it is mounted onto a weapon. Prior to SAT alignment if the weapon is not zeroed, the soldier may want to return the weapon sights to mechanical zero. Once attached to the correct weapon and aligned, the SAT does not require the soldier to zero his weapon prior to training or make any adjustments to his weapon. Also, once aligned, the SAT retains alignment for extended periods of time even under harsh training conditions.

TM 23-6920-706-10

2-41

b. The objective of the alignment process is to align the laser of the SAT to the sight picture of the shooter, so that when force-on-force engagements are conducted in the field the SAT laser beam replicates operational characteristics of the weapon on which the SAT is mounted. Alignment of the SAT does not alter the shooter’s sights or the weapon.

c. The process of aligning the laser transmitter is similar to live fire zeroing practice. Alignment is required as different weapons and users have different sight offsets. While aligning, the elevation (EL) and azimuth (AZ) alignment knobs on the transmitter are rotated to move the laser beam to the target. No changes are made to the weapon on which the SAT is mounted.

2.21.1 Alignment of the SAT using the Mirror Alignment Jig Kit Assembly. The mounting and alignment process using the Mirror Alignment Jig Kit Assembly process should take less than two (2) minutes. Use of two people for this process is the preferred method with the shooter holding and aiming the weapon while the other person adjusts the alignment controls. The process should have the following items.

• Soldier Infantry Weapon with SAT installed • Controller Device or H-harness • Mirror Alignment Jig Kit Assembly • A 2 meter area to complete the procedure • Sand bags or equivalent to steady weapon

2.21.1.1 Mirror Alignment Jig Kit Assembly Set-up. The MAJiK assembly is housed in its own transit case. Its transit case has an instructional placard, a protective cloth bag for mirror, and may hold an optional torque wrench and dry fire trigger.

a. To set up the MAJiK, complete the following steps using Figure 2-21 as a reference:

(1) Open Case (refer to mirror down view of Figure 2-21).

(2) Ensure case is reasonably level and shaded so red laser may be seen.

(3) Pull target arm to vertical and then horizontal to a level position

(4) Pull target card fully extended to vertical.

(5) Rotate mirror to vertical and remove cloth protective bag if necessary (refer ready to use in Figure 2-21). Cloth may be used to “dust off” mirror.

(6) Raise the case if necessary so weapon sights are level with mirror center for taller weapons.

(7) If the torque wrench and/or dry fire trigger are present in the case and interfere with deployment if the target arm, remove as necessary.

(8) Reverse actions to properly stow MAJiK components to a transit condition.

Figure 2-21. Mirror Alignment Jig Kit Assembly Set Up.

2.21.1.2 SAT Alignment by Mirror Alignment Jig Kit Assembly.The following are step-by-step procedures to align a SAT using the MAJiK Assembly:

a. Set up MAJiK per instructions in paragraph 2.21.1.1.

b. Verify SAT installed in accordance with SAT installation discussed in paragraph 2.20. c. Verify the SAT is associated with the shooter’s H-harness. d. Put the end of the weapon BFA slightly left and behind the target card with the weapon barrel

perpendicular to the mirror as shown in Figure 2-22. The shooter will be slightly left of the target board and mirror.

NOTE

As long as the SAT is behind the target card the distance behind the target card is not important as long as the shooter can see the red laser on the target card.

e. While looking through the weapon sights, locate the reflection of the target board crosshairs through the mirror.

f. Choose the appropriate target board crosshairs (typical view in Figure 2-23) for aiming:

(1) Aim the M16/M4/M24/M107/M2 (top mount) at the crosshair by the number “1”.

(2) Aim the M240/M249/M110 (left mount with optics) at the crosshair to the right of the number “1”.

(3) The crosshair by the number “2” is not used.

NOTE FOR IR MODE ONLY

A good IR link is required to turn on Red Laser. Position SAT at 11 o’clock position slightly high to H-harness Comms Module to get good communications.

i. For the flat alignment knob SAT configuration, use a flat edge object like a coin or flat screwdriver to move the red laser. For the knurled alignment knob SAT configuration, pull out the adjustment knobs on the SAT to move the red laser position on the target board.

j. Turn the AZ & EL knobs moving the red laser until the red laser is top center on the iron sight and card crosshairs or in the center of the cross hairs. Refer to Figure 2-13 for location of alignment knobs.

k. For the flat alignment knob SAT configuration, leave the knobs as is. For the knurled alignment knob SAT configuration, push in knobs to secure. In this position, alignment knobs will spin freely without changing alignment.

l. Turn off the red laser. At the “Red Laser Enter to Toggle (off or on)” display. PRESS: Select ↵ Button or use controller device to turn CONTROLLER MODE OFF.

m. The SAT is now aligned and ready to use.

NOTE

If the SAT cannot be easily aligned or if the visible red laser cannot be brought to the alignment assembly target board by full rotation of the alignment knobs, return the SAT for repairs.

CHAPTER 3 OPERATOR/CREW MAINTENANCE

3.1 GENERAL.

Operator preventive maintenance checks and services (PMCS) are described in the following “Inspection” and “Cleaning” sections. They are to be performed as pre and post use activities.

MILES IWS equipment should not be opened in the field. In this document, maintenance of the equipment is restricted to the type of maintenance that can be carried out by operators easily in the field.

Faults that cannot be rectified in the field will need to be referred to the approved LCCS workshop or the manufacturer. Faulty units must be clearly labelled and returned for maintenance.

The basic diagnostic procedures that can be applied in the field will aid in elimination of elementary errors in operation of the equipment and identification and correction of minor faults.

All equipment should be inspected and cleaned after the conclusion of an exercise and stored properly so that it should not normally need cleaning again before the commencement of the next exercise. However, before all use, the equipment should be inspected and if found dirty, should be cleaned.

3.2 IWS COMPONENT PREVENTIVE MAINTENANCE CHECKS AND SERVICES (PMCS).

The soldier operator should perform the following preoperational checks shown in Table 3-1.

Table 3-1. IWS PMCS.

ITEM TASK FREQUENCY 1 H-harness Inspect for damage. Daily 2 H-harness Perform system BIT. Daily 3 H-harness Ensure detectors covers are wiped clean. Daily 4 H-harness Ensure HCU display is wiped clean. Daily 5 H-harness Report damaged equipment. As required 6 Halo Inspect for damage. Daily 7 Halo Perform system BIT.

TM 23-6920-706-10

3-2

3.3 H-HARNESS.

The HCU, comms module, and speaker are sealed and must not be opened in the field. In this document, the maintenance of the H-harness is limited to the following:

a. Inspection

b. Cleaning

c. Troubleshooting

d. Function Tests

e. BIT Tests

3.3.1 Inspection. The following paragraphs identify problems, which require the equipment to be generally put in for servicing.

3.3.1.1 General H-harness/Halo and Laser Detectors.

a. Battery Cap: Cracks, bent, stripped thread, missing screws, damaged rubber seal.

b. Laser Detectors/Lens Caps: Cracked, broken or missing, wiring exposed. Check that none of the detector caps are damaged or missing. If there is any damage that cannot be rectified in the field, label the H-harness or halo non-usable and return it for repairs.

c. Fabric: Torn or cut. Check that the material of the H-harness is not torn or severely ground down or torn; there must be no exposed or protruding wires. Check that there are no missing or damaged clips or fasteners.

d. Straps: Ripped stitching, etc. Check that the different parts of the H-harness, including the straps and Velcro patches, are still securely stitched together.

If there is any damage to the H-harness, label the H-harness non-usable and return it for repair. At the conclusion of an exercise, the H-harness should be thoroughly inspected and cleaned.

3.3.1.2 H-harness HCU.

a. Case: Missing or loose screws, damaged/cracked. Inspect the exterior case of the control box. Check that the screws are present and secure (loose screws would imply that the case seal has been breached).

b. Labels: Loose or unreadable.

c. Windows: Dirty, badly scratched, or damaged. Check that the optical port lens is clean and free of scratches, and is not damaged in any way.

d. LCD Display: Dirty, badly scratched, or damaged. Check that the LCD Display is free from scratches and is legible, and not cracked or damaged. Check that the buttons are mechanically functional.

TM 23-6920-706-10

3-3

e. Display buttons: Broken or not functioning.

f. LEDs: Broken or missing lens. No LED flashes when a known good battery is inserted.

If there is any damage that cannot be rectified in the field, label the H- harness non-usable and return it for repairs

3.3.1.3 Speaker.

a. Speaker exterior: Damaged appearance.

b. Speaker: No audio sounds when the H-harness has known good batteries.

c. Kill LED: Broken or missing lens.

Since the speaker is protected by a fabric cover, if the speaker has suffered damage or if there are no audio cues, return it for cleaning or repair.

3.3.1.4 Comms Module.

a. Comms Module: Damaged appearance.

b. Front Lens: Damaged appearance.

Since a fabric cover protects the comms module, if the cover has suffered extensive damage, return it for damage disposition.

3.3.2 Cleaning. The man-worn H-harness and halo must be thoroughly cleaned by using a cloth or a brush that is dampened with soapy water, then use a cloth or brush dampened with clean water, and finally dry with a soft clean cloth.

It then should be dried and stored properly after an exercise. The H-harness must be inspected before the commencement of the next exercise. If the inspection reveals that the device has not been properly cleaned, then the necessary cleaning will have to be repeated.

a. Cleaning on the following must be carried out:

(1) H-harness and Halo Laser Detectors

(2) Exterior HCU case

NOTE

Do not using dry cleaning solution to clean any IWS item.

3.3.2.1 H-harness and Laser Detectors.

a. Remove all debris and mud from the H-harness. Dried mud and debris can be removed from the H-harness material by means of a stiff brush. Wipe the caps of the laser detectors with a moist

TM 23-6920-706-10

3-4

soft clean cloth. Warm soapy water may be used if necessary and dry afterwards with a soft clean cloth.

b. After cleaning, ensure that the H-harness is completely dry.

3.3.2.2 HCU.

a. Remove all debris and mud from the HCU. Dried mud can be removed by means of a stiff brush.

b. Wipe the boxes with a moist soft clean cloth. Remove all debris and mud from the LCD Display and the optical port lens. Warm soapy water may be used if necessary; dry afterwards with a soft clean cloth. Finally, wipe the optical port lens of the HCU with either a lens paper or a soft dry clean cloth.

c. After cleaning, ensure that the H-harness is completely dry.

3.3.3 Troubleshooting.

a. The following situations may be corrected in the field:

(1) H-harness or halo fails to respond/low battery indication.

(2) Inability to transfer data.

(3) H-harness/halo fails to react to near misses and kills.

(4) H-harness cannot be reset.

b. When a fault involves the interaction of the H-harness with other IWS components, it is assumed that the possibility of a fault in the other component has already been eliminated.

3.3.3.1 H-harness/ Halo Fails to Respond/Low Battery Indicator.

a. The H-harness achieves in excess of 100 hours of service from the batteries; prolonged storage after active use may result in battery going “dead.” The HCU menu user information submenu displays the battery condition status. With the battery LOW indication displayed on the HCU, there is a 3-minute period to replace the batteries without a “cheat kill” event being recorded in the log.

b. If the H-harness does not respond to any laser stimuli (e.g., kill, resurrect, near miss) from a controller device, the HCU batteries may have gone bad. Replace the batteries in the battery compartment. If the halo does not respond to any stimuli (e.g., kill, resurrect, near miss) from a controller device, the halo battery may have gone bad. Label the halo non-usable and return it for repair.

c. Check to see that the battery cap is clean from dirt, the battery is good, and the cap is tightened properly. If after replacing the batteries and properly replacing the cap on the battery compartment, the HCU does not power on, label the H-harness non-usable and return it for repair.

d. In a rare instance, a halo may not respond if it has been totally at rest for longer than 15 minutes. It has a motion sensor and sleep mode that powers down the electronics for periods of storage

TM 23-6920-706-10

3-5

conditions to preserve battery life. Moving the halo will activate it so it provides the correct responses. Wait 10 seconds between attempts. If there is no HALO BATT status on the HCU display after repeated attempts then replace the Halo.

3.3.3.2 Inability to Transfer Data.

a. If there is difficulty in transferring data between the HCU and the TDTD device, the cause of the problem might be, one of the following:

(1) Optical ports are not correctly aligned.

(2) Optical port lenses are dirty.

(3) HCU batteries are dead.

b. Ensure that the TDTD and HCU optical ports are aligned correctly. The notch of the TDTD optical port must engage in the recess of the HCU. Clean the optical port lenses if these are dirty. Replace the battery if it is flat. If the problem persists, label the H-harness non-usable and return it for repair.

3.3.3.3 H-harness Fails to react to Near Misses and Kills.

a. If the H-harness fails to react to near-misses or kills inflicted by a transmitter or a Controller Device, the cause of the problem might be, amongst others, one of the following:

(1) H-harness has already sustained a ‘kill’ or ‘near miss.’

(2) Detector covers are obscured or missing.

(3) SAT or Controller Device is too close to H-harness. Particularly in IR mode SAT and H-harness Comm Module can not communicate. Line of sight around a meter is best.

(4) H-harness ID code equals ID code of the SAT currently associated with the H-harness.

b. Clean the detector covers if they are dirty. Ensure that the SAT or Controller Device is further than two meters from the H-harness; if the SAT or Controller Device is too close and is not aimed directly at a detector, the laser beam might not be detected (beam too narrow).

c. The third fault is an operational error and is easily corrected; the H-harness will not react to a SAT it is associated with.

d. If the problem persists even after the foregoing aspects have been addressed, label the H-harness non-usable and return it for repair.

3.3.3.4 H-harness Cannot be Reset.

a. If a Controller Device is unable to reset the (a disabled or ‘killed’) H-harness, the cause of the problem might be one of the following:

(1) Detector covers are obscured or missing.

TM 23-6920-706-10

3-6

(2) Controller Device is too close to the H-harness.

b. Clean the detector covers if they are dirty. Replace damaged or missing covers. Ensure that the Controller Device is further than two meters from the H-harness; if the Controller Device is too close and is not aimed directly at a detector, the laser beam might not be detected.

c. If the problem persists, label the H-harness non-usable and return it for repair.

3.3.4 Function Tests.

a. The aim of the function test of the H-harness is to verify that the H-harness reacts correctly to valid kill, near-miss, and reset events produced by a Controller Device. This includes the proper functioning of the HCU event logging and indicating a low battery condition.

b. Ensure that the Controller Device is fully functional.

3.3.4.1 Function Test Procedure.

a. Power up the H-harness.

b. Mount the H-harness in an upright position. Set the Controller Device for the KILL function of the Laser Fire mode. From a distance of about five meters, aim the Controller Device at the H-harness and pull the trigger. The H-harness speaker should emit the KILL tone. Lay the H-harness flat. The KILL tone should cease.

c. Set the controller device for the RESET function of the laser fire mode. From a distance of about five meters, aim the controller device at the H-harness and pull the trigger. The H-harness speaker should emit the RESET tone.

d. Set the CONTROLLER DEVICE for the NEAR-MISS function of the laser fire mode. From a distance of about five meters, aim the CONTROLLER DEVICE at the H-harness and pull the trigger. The H-harness speaker should emit the NEAR-MISS tone.

3.3.5 BIT Tests.

a. The H-harness conducts a self-BIT test upon power-up or when the battery is replaced. (Refer to paragraph 2.6.).

b. A self-conducted BIT test by the soldier may be accomplished by performing the commanded BIT procedure in paragraph 2.9.

3.4 SAT.

The SAT is a sealed unit that should not be opened in the field. In this document, maintenance of the SAT is limited to the following:

a. Inspection.

b. Cleaning.

c. Troubleshooting.

(1) Exterior of the SAT Case

(2) Optics

(3) Flash Sensor Window

(4) Alignment Knobs

(5) Clamp

3.4.1.2.1 Exterior of the SAT Case. Inspect the exterior of the transmitter case. Check that there are no cracks in the case or any other signs of damage. Check that the serial-number label is still attached and is still legible. Similarly, check the labels on the rear wall. Check that all screws securing the base of the case are all present and that the base is firmly attached. (Loose screws imply that the sealing of the case has been breached.) Finally, check that both adjustment knobs are still firmly attached and are undamaged. If there is any damage, label the transmitter non-usable and return it for repair.

3.4.1.2.2 Optics.

a. Inspect the lens of the laser and the lens of the comms port. (The comms port houses the IR link and the Indication LED.)

TM 23-6920-706-10

3-8

b. Check that the lenses are clean, free of scratches, and are not damaged. If there is any damage, label the SAT non-usable and return it for repair.

3.4.1.2.3 Flash Sensor Window. Check that the lenses are clean, free of scratches, and are not damaged in any way. If there is damage, label the SAT non-usable and return it for repair.

3.4.1.2.4 Alignment Knobs. Inspect the cavities in the two alignment knobs. If any dirt has accumulated behind them, it should be removed as explained in the “Cleaning” section below.

3.4.1.2.5 Clamp.

a. Inspect the clamp that fits the SAT to the weapon. When the clamp is fitted to the SAT, it should secure the SAT firmly onto the weapon.

b. Check that there are no cracks or missing or broken parts. If there is any damage, return the clamp for replacement.

3.4.2 Cleaning. The SAT must be thoroughly cleaned and stored properly after an exercise. The device must be inspected before the commencement of the next exercise. If the inspection reveals that the device has not been properly cleaned, then the necessary cleaning will have to be repeated.

a. Cleaning on the following must be carried out:

(1) Exterior of the SAT Case

(2) Flash Sensor Window

(3) Alignment Knobs

3.4.2.1 Exterior of the SAT Case. Remove all debris and mud from the exterior of the SAT case. Warm soapy water or moist soft cloth may be used for this purpose if necessary. Wipe off any grit on the lenses of the laser and the comms port. Dry the case afterwards with a soft clean cloth. Wipe the lenses with either lens paper or a dry soft clean cloth. After cleaning the case, ensure that the case is completely dry.

3.4.2.2 Flash Sensor Window. Remove all debris and mud from the flash sensor window. Wipe the lenses with either lens paper or a dry soft clean cloth. After cleaning, ensure that it is completely dry.

3.4.2.3 Alignment Knobs. If dirt has accumulated behind the cavities of the alignment knobs, try removing it with a sharp object or use warm soapy water. Dry it thoroughly with a soft clean cloth.

3.4.3 Troubleshooting.

a. The following situations may be corrected in the field:

(1) SAT fails to respond/low battery indicator.

(2) SAT fails to associate with H-harness.

(3) SAT fails to fire laser beam when trigger is pulled.

TM 23-6920-706-10

3-9

(4) Inability to inflict kills or near-misses on other H-harnesses.

b. If the problems persist even after following the diagnostics below, label the SAT non-usable and return it for repair.

3.4.3.1 SAT Fails to Respond/Low Battery Indicator.

a. The SAT is designed to provide long service from its battery (in excess of 100 hours), but prolonged storage and active use may result in the battery going ‘dead/flat.’ A Low Battery warning will be indicated by the SAT LED remaining ON and steady.

b. Check to see that the battery cap is clean from dirt, the battery is good, and the cap is tightened properly. If after replacing the battery and properly closing the battery compartment with the cap, return the SAT for repair.

3.4.3.2 Fails to Associate with a H-harness.

a. Failure to associate can be caused by any of the following:

(1) Faulty H-harness.

(2) Wrong position of H-harness and SAT.

(3) H-harness has been killed.

(4) H-harness is already associated.

(5) IR link lenses are dirty.

(6) Battery is faulty.

(7) SAT/HCU processors are “asleep.”

b. Ensure that the SAT is fitted to the weapon properly, the weapon is held in a normal firing position, and the halo is worn correctly.

c. Confirm H-harness/SAT association by manually pressing to WEAPON TOKEN display on the HCU User Info submenu. This allows the soldier to check his weapon’s association by seeing the SAT LED flash.

d. Clean the IR link lenses if these are dirty.

e. Remove and re-install batteries into HCU and/or SAT.

f. Replace the batteries if the problem persists.

3.4.3.3 SAT Fails to Fire Laser Beam.

a. If the "FIRE" LED fails to illuminate when the trigger of the weapon is pulled, this indicates that the laser beam has not been fired. Assuming that the LED itself has not failed, the cause of the problem might be one of the following:

TM 23-6920-706-10

3-10

(1) Battery is faulty.

(2) Flash sensor is faulty, or the window covered in (carbon) deposits from percussion firing activity.

(3) The SAT is not associated with a H-harness.

(4) Blank Fire Adaptor (BFA) blocked or not fitted correctly.

(5) Dry fire trigger not mounted directly into the SAT IR port window.

(6) SAT processor is “asleep.”

b. Remove and re-install batteries into SAT.

c. Replace the battery if faulty.

d. Inspect the flash-sensor window for surface deposits; clean as necessary.

e. Check that the SAT is associating with the H-harness. If not, refer to previous section.

f. Check that the BFA is clear and fitted properly. Check that BFA opening is facing the correct way.

g. The weapon BFA must be functioning properly; if the BFA becomes blocked, then the blank firing gases are exhausted out of the weapon’s pressure port and the SAT flash/bang detector will not see any significant flash signal.

3.4.3.4 Inability to Inflict Kills or Near-Misses on H-harness.

a. If the “FIRE” LED illuminates (indicating that a laser beam has been fired upon pulling the weapon’s trigger) but the SAT appears unable to inflict kills or near-misses on an opponent's H-harness despite careful aiming of the weapon, the cause of the problem might be one of the following:

(1) SAT loosely clamped.

(2) Incorrect SAT clamp fitment to the weapon.

(3) SAT ID code equals opponent's H-harness ID code.

(4) Dirt, accumulation on laser lens, reducing power.

(5) SAT is misaligned with respect to weapon.

b. If the SAT is insecurely clamped to the barrel, tighten the clamping screws with torque wrench.

c. If incorrect, and the wrong SAT/clamp is fitted to the weapon, change it with the correct one.

d. If the clamp was insecure or the weapon type incorrect, rectify the fault and realign the SAT.

TM 23-6920-706-10

3-11

e. Remove any dirt/accumulation on laser lens that may be reducing the laser power. Also, the laser lens must not be damaged, etc.

f. If the problem persists, label the SAT non-usable and return it for repair.

3.4.3.5 Dry Fire Trigger does not make SAT fire laser beam.

a. If the "FIRE" LED fails to illuminate when the trigger of the weapon is pulled, this may indicate that the laser beam has not been fired due to a DFT problem. If the SAT functions in blank fire and/or the DFT functions on another, the cause of the problem might be one of the following:

(1) DFT is not mated correctly on SAT.

(2) Dry fire trigger not mounted directly into the SAT IR port window.

(3) The SAT is not associated with an H-harness.

(4) DFT Battery is faulty.

(5) DFT circuit board is faulty.

b. Reconnect the DFT to the SAT ensuring that the IR windows are aligned.

c. Verify that the SAT is associated with an H-harness.

(1) Disassociate the SAT from the H-harness and verify HCU displays Weapon Not Ready.

(2) Associate the SAT to the H-harness and verify HCU displays Weapon Ready.

(3) Using the DFT, dry fire the SAT and verify the “FIRE” LED illuminates.

d. Return DFT to support contractor for repair.

3.4.4 SAT Function Test.

a. Insert a new battery into the SAT. To indicate BIT passed, the LED in the rear window should illuminate for approximately 1 second and then turn off when the battery is inserted

(1) for LED indications see Section 2.19, Table 2-5.

b. After 30 seconds verify the LED in the rear window does not stay on.

(1) If the LED stays on replace the SAT and restart the functional test.

c. Associate the SAT to the harness (see Section 2.8).

d. Confirm H-harness/SAT association by manually pressing to WEAPON TOKEN display on the HCU User Info submenu. This allows the Soldier to check his weapon’s association by seeing the SAT LED flash.

e. If not installed, install a dry fire trigger.

TM 23-6920-706-10

3-12

f. Dry Fire the SAT at a harness and verify the FIRE LED illuminates and the harness receives an event (i.e., hit, kill, or near miss). This allows the Soldier to verify the SAT is functional.
