Hand Grenades

Hand GrenadesGary's U.S. Infantry Weapons Reference Guide

DESCRIPTIONHand grenades can be classified as:

Fragmentation. These grenades are used to produce casualties by high velocity projection of fragment. Historically, the most important hand grenade has been the fragmentation grenade, which is the soldier's personal indirect weapon system.

Fragmentation grenades are fused with either impact detonating or delay detonating fuzes composed of a striker, primer and delay charge detonator. A booster may be included. A safety lever, curved to conform to the shape of the grenade body, is hooked to the top of the fuze. The lever is held in place by a safety pin (pull ring), which protects the striker from action of the striker spring. Safety pin removal is required immediately before the grenade is thrown.

Illuminating. This grenade is used to provide illumination of terrain and targets. Because the illuminant compound burns with a very hot flame, this type can also be used for incendiary purposes against flammable targets.

A typical illuminating grenade is similar in size and function to burning-type chemical grenades. It consists of three basic components: a thin, sheet-metal body, an illuminating charge, and a special, igniter-type fuze. The igniter consists of a quick-match contained in a bushing. The illuminating charge consists of a pyrotechnic composition, a first-fire composition and an igniter charge.

Chemical. These grenades are used for incendiary, screening, signaling, training, or riot control purposes.

Burning-type grenades are usually fitted with igniting fuzes which function with a 1.2 to 2-second delay. Functioning of the fuze ignites the first-fire (starting) mixture which ignites the filler. The burning filler creates sufficient pressure to blow tape covering the emission holes (gas ports) free and allow the chemical agent (riot control gas, smoke)

to escape.

WARNING: Burning-type grenades burn oxygen. Standard protective masks filter particles but will not supply oxygen. Therefore, burning grenades will not be used in enclosed or confined spaces.

Bursting-type grenades are fuzed with delay fuzes which contain high-explosive detonators. The detonators rupture the grenade body and disperse the filler (tear gas, white phosphorus). Although this type of grenade functions by bursting, it creates the same effect as burning grenades.

The current U.S. policy governing the use of CS and other riot-control munitions is found in Executive Order 11850, 8 April 1975. CS irritant gas (tear gas) may be employed in a combat zone with the approval of a higher authority. U.S. forces will employ CS in wartime defensively only to save lives as approved by the President. The Secretary of Defense may authorize the use of CS to protect and recover nuclear weapons. CS may be used on military installations (domestic and overseas), embassy grounds, and so forth, in war and in peace.

The U.S. and many other countries do not consider CS or other control agents to be chemical warfare weapons; however, some other countries do not draw a distinction. Riot-grenade hand grenades include the ABC-M7A2, ABC-M7A3, and the M47 CS.

Offensive. This grenade is used for blast effect. Offensive grenades are much less lethal than fragmentation grenades on an enemy in the open, but they are very effective against an enemy within a confined space.

This type of grenade has a non-metallic body (cardboard, fiberglass) loaded with a high explosive filler. It employs a delay detonating fuze. Some metal fragments from the fuze may be projected.

Anti-tank. AT grenades are designed to be thrown at armored vehicles. They have a shaped-charge warhead and are stabilized by a spring-deployed parachute or cloth streamer. AT grenades use impact fuzing.

Non-lethal. Stun hand grenades are used as diversionary or distraction devices during building and room clearing operations when the presence of noncombatants is likely or expected and the assaulting element is attempting to achieve surprise.

Practice and training. A typical practice grenade contains a small spotting charge of black powder and is fuzed with a 4 to 5-second delay igniting fuze. This type of grenade is used to simulate operation and functioning of service grenades.

Training grenades are unfuzed and completely inert. They resemble service rounds in size and shape, and are used for training in handling and throwing.

The hand grenade is made up of the following components:

Body. The body contains filler and, in certain grenades, fragmentation. Filler. The filler is composed of a chemical or explosive substance,

which determines the type of hand grenade for employment factors. Fuze Assembly. The fuze causes the grenade to ignite or explode by

detonating the filler.

OPERATION

1. Release of the safety clip and removal of the safety pin permits release of the safety lever.

2. Once the grenade is thrown, the pressure on the safety lever is released, and the striker is forced to rotate on its axis by the striker spring, throwing the safety lever off.

3. The striker then detonates the primer, and the primer explodes and ignites the delay element.

4. The delay element burns for the prescribed amount of time then activates either the detonator or the igniter.

5. The detonator or igniter acts to either explode or burn the filler substance.

FUZESThe two types of fuzes used in current U.S. hand grenades are detonating and ignition. Both function in the same manner; the difference is how they activate the filler substance.

Detonating Fuze. Detonating fuzes explode within the grenade body to initiate the main explosion of the filler substance. Detonating fuzes

include the M204A1, M204A2, M206A2, M213, M228, and the C12 integral fuze.

M204A1 and M204A2 fuzes.

These fuzes are used with the M26, M26A1, and M61 fragmentation grenades. The delay element is a powder train requiring 4 to 5 seconds to burn to the detonator. The detonator sets off the filler.

M206A2.

This fuze is used with the MK3A2 offensive hand grenade, commonly referred to as the concussion grenade. The M206-series of fuzes is similar to the M204-series, except for the safety lever. The M206 has a straight safety lever, while the M204 safety lever is curved. The delay element is a powder train requiring 4 to 5 seconds to burn to the detonator.

M213 fuze.

The M213 fuze is designed for use with the M67 fragmentation grenade. It has a safety clip. The standard delay element is a powder train requiring 4 to 5 seconds to burn to the detonator. In some cases, the delay element may vary from less than 4 seconds to more than 5 seconds due to defective fuzes.

Unit cost: $5.73 (Fiscal Year 2005).

M228 fuze. The M228 fuze is used with the M69 practice grenade to replicate the fuze delay of the M67 fragmentation hand grenade. The time delay element is a powder train with a 4- to 5-second delay burn. In some cases, however, the delay element may vary from less than 4 seconds to more than 5

seconds due to defective fuzes.

This is a training unique item; not used in combat.

Type Classification Date: 1971. Unit cost: $4.16 (Fiscal Year 2005).

C12 integral fuze.

This fuze is an integral part of the M25-series riot control hand grenades. The fuze consists of a firing pin (screwed to the base of the grenade body), an arming sleeve, and a slider assembly. The slider assembly contains a delay element of 1.4 to 3 seconds and a small detonator. It functions as follows:

When the safety pin is removed, the arming sleeve is held in place with the thumb.

When the arming sleeve is released, the slider assembly is forced downward toward the firing pin under pressure of the firing spring.

At the bottom of the fuze well, the slider strikes the firing pin and ignites the delay element which, in turn, sets off the detonator.

The detonator bursts the grenade body and disperses the riot control agent over an area about 5 meters in diameter.

Igniting Fuze. Igniting fuzes are designed for use with chemical hand grenades. They burn at high temperatures and ignite the chemical filler.

M201A1 pyrotechnic delay-igniting fuze.

The M201A1 is designed for use with the AN-M83HC white smoke grenade, the AN-M14 TH3 incendiary grenade, and the M18 colored smoke grenade. This fuze is interchangeable with any standard firing device. The time delay element is a powder train requiring 1.2 to 2 seconds to burn to the igniter. The igniter ignites the filler or a pyrotechnic starter with a violent burning action and expels the filler from the grenade body.

M201A1 MOD 2. Designed to be non-fragmenting. Used on the ABC-M7A2 CS, ABC-M7A3 CS, and M84 stun hand grenades.

M201A1-1.

Used on the GG04 rubber ball grenade and the GG05 practice grenade body.

Grenade, Hand, Riot, CS, ABC-M7A2Grenade, Hand, Riot, CS, ABC-M7A3

The ABC-M7A2 and ABC-M7A3 riot-control hand grenades contain only CS as a filler. They differ only in the amount of filler and the form of the CS they contain. The ABC-M7A2 grenade has 5.5 ounces of burning mixture and 3.5 ounces of CS in gelatin capsules. The ABC-M7A3 has 7.5 ounces of burning mixture and 4.5 ounces of CS pellets.

The bodies of both grenades are sheet metal with four emission holes at the top and one at the bottom. Both grenades have gray bodies with red bands

and markings. These grenades do not have safety clips.

ABC-M7A3 Unit cost: $175 (Fiscal Year 2005).

Grenade, Hand, Riot, CN1, ABC-M25A1

Obsolete. The ABC-M25A1 riot control hand grenade is a bursting munition with an integral fuze.

All fillers are mixed with silica aerogel for increased dissemination efficiency.

The M25 series of riot-control hand grenades have a radius burst (visible cloud grenade) of about 16 feet (5 m), but fragments of the grenade are occasionally projected up to 82 feet (25 m).

The grenade has a gray body with red band and red markings.

Grenade, Hand, Riot, CN1, ABC-M25A2Grenade, Hand, Riot, CS1, ABC-M25A2

ABC-M25A2 CS1Obsolete. The ABC-M25A2 riot control hand grenade is a bursting munition with an integral fuze. The M25A2 grenade is an improved version of the M25A1 grenade. The two grenades differ primarily in body construction.

All fillers are mixed with silica aerogel for increased dissemination efficiency.

The M25 series of riot-control hand grenades have a radius burst (visible cloud grenade) of about 16 feet (5 m), but fragments of the grenade are occasionally projected up to 82 feet (25 m).

The grenade has a gray body with red band and red markings.

Grenade, Hand, Smoke, HC, AN-M8

The AN-M8 HC grenade is used to produce dense clouds of white smoke for signaling and screening. Note that this grenade was listed as obsolete in the September 2000 FM 3-23.30, while the latest June 2005 release of the manual lists the grenade as currently in service.

WARNING: The AN-M8 HC grenade produces harmful hydrochloric fumes that irritate the eyes, throat, and lungs. It should not be used in closed-in areas unless soldiers are wearing protective masks.

WARNING: Damaged AN-M8 HC grenades that expose the filler are hazardous. Exposure of the filler to moisture and air could result in a chemical reaction that will ignite the grenade.

The grenade has a light green body with black markings and a white top.

Grenade, Hand, Incendiary, TH3, AN-M14

The AN-M14 TH3 incendiary hand grenade is used to destroy equipment or start fires. It can also damage, immobilize, or destroy vehicles, weapons systems, shelters, or munitions.

A portion of thermate mixture is converted to molten iron, which burns at 4,000° Fahrenheit. The mixture fuzes together the metallic parts of any object that it contacts. Thermate is an improved version of thermite, the incendiary agent used in hand grenades during World War II. The thermate filler can burn through a 1/2-inch homogenous steel plate. It produces its own oxygen and burns under water.

WARNING: Avoid looking directly at the incendiary hand grenade as it burns. The intensity of the light is hazardous to the retina and can cause permanent eye damage.

The grenade is gray in color with purple markings and a single purple band (current grenades). Under the standard color-coding system, incendiary grenades are light red with black markings. This grenade does not have a safety clip.

Grenade, Hand, White Smoke, TA, AN-M83

The AN-M83 TA white smoke hand grenade is used for screening the activities of small units and for ground-to-air signaling.

The grenade has a forest green body with light green markings, a blue band, and a white top.

Grenade, Hand, Rubber Ball, Non-Lethal, GG04

The GG04 rubber ball grenade is used in crowd control situations where the use of non-lethal force is desired. The rubber ball grenade is designed to be hand-thrown or muzzle-launched from a 12-gauge shotgun.

The GG04 is a multiple projectile, flash-bang grenade with 100 .25-caliber hard rubber pellets. The grenade has a fuze delay of 2.8 to 3 seconds with a flash measuring approximately 1 million CP and 180 decibels at 3.5 feet. At detonation, rubber pellets are dispatched at 360° with an effective range of 2 to 3 meters and a maximum engagement range of 15 to 20 meters.

The grenade body is a rubber sphere that contains a fuze well liner.

The grenade is black with white lettering.

Fielded: 1998. Unit cost: $30 (Marine Corps Fiscal Year 2003).

Grenade, Hand, Practice, Non-Lethal, GG05

The GG05 is designed to replicate the live GG04 rubber ball grenade. It is made of durable rubber and can be hand-thrown or muzzle-launched from the 12-gauge shotgun. The body can be reloaded up to 25 times and is a component of a practice grenade assembly, consisting of the body and a M201A1-1 practice grenade fuze.

The grenade body is a rubber sphere that contains a fuze well liner and is filled with .50 caliber rubber pellets. The rubber ball pellets remain within the body.

The GG05 is blue in color. The fuze has a blue safety lever with a brown stripe.


Fielded: 2002. Unit cost: $11 (Marine Corps Fiscal Year 2003).

Grenade, Hand, Smoke, WP, M15

The M15 white phosphorous grenade is a bursting type grenade used for signaling, screening, and incendiary purposes.

WARNING: All friendly personnel within the 56 foot (17 m) bursting radius should be in a covered position to avoid being struck by burning particles. The WP filler burns for about 60 seconds at a temperature of 5,000° Fahrenheit. This intense heat causes the smoke produced by the grenade to rise quite rapidly, especially in cool climates. This makes the M15 grenade less desirable for use as a screening agent.

The grenade is grey with one yellow band and yellow markings.

Grenade, Hand, Smoke, Green, M18Grenade, Hand, Smoke, Yellow, M18Grenade, Hand, Smoke, Violet, M18Grenade, Hand, Smoke, Red, M18

The M18 colored smoke hand grenade is used for ground-to-air or ground-to-ground signaling.

The body consists of a sheet steel cylinder with emission holes:

Four emission holes at the top and one at the bottom (older production).

Four emission holes at the top and none at the bottom (more recent production).

No top emission holes and one taped bottom hole (current and recent production).

The holes allow smoke to escape when the grenade is ignited.

WARNING: Burning type grenades burn oxygen. Standard protective masks filter particles but will not supply oxygen. Therefore, burning grenades should not be used in enclosed or confined spaces.

The M18 grenade is light green with black markings. The top of the grenade indicates the smoke color (red, yellow, green, or violet).

Yellow smoke is sometimes difficult to see in urban areas. Newer versions of yellow smoke grenades are more visible than the old type.

The body contains a primer, first fire mixture, pyrotechnic delay column, and ignition mixture. Assembled to the body are a striker, striker spring, safety lever, and safety pin with pull ring. The split end of the safety pin has an angular spread.

This is a training standard item used in both training and combat.

Type Classification Date: Early 1950's. Unit cost: $43.20 (Fiscal Year 2005).

Grenade, Hand, Fragmentation, M26Grenade, Hand, Fragmentation, M26A1

Obsolete. These grenades are used to supplement small arms fire against an enemy in close combat. They produce casualties through the high-velocity projection of fragments.

The M26 and M26A1 fragmentation grenades have been reclassified as the M61 under the product improvement program that added an attached safety clip feature.

WARNING: Although the casualty-producing radius is 50 feet (15 m), fragmentation can disperse as far away as 755 feet (230 m).

These grenades have an olive drab body with a single yellow band at the top and yellow markings, which indicate a high-explosive filler.

Grenade, Hand, Riot, CS, M47

The M47 grenade is a special-purpose, burning type munition used for the control of riots and counterinsurgencies. This grenade is a nonlethal,

incapacitating type munition that contains non-persistent CS agent.

The M47 consists of a rubber body assembly with a fuse delay of about 2 to 3 seconds before ignition. Discharge of the CS results in a random "skittering" of the grenade. The speed of the discharge through the ports prevents target personnel from picking up the grenade and throwing it back. The manner in which this grenade explodes also eliminates fragmentation side effects and minimizes fire hazards.

The top half of the grenade contains the fuze, and bottom half contains the filling hole and exhaust port.

Gray with red band and black markings.

Grenade, Hand, Fragmentation, M61

This type of grenade was developed to replace the earlier model fabricated with a deeply serrated cast iron body (the pineapple World War I grenade).

Fragments are produced by a serrated wire coil fitted to the inside of the grenade body.

WARNING: Although the killing radius of this fragmentation grenade is 16 feet (5 m) and the casualty-producing radius is 50 feet (15 m), fragmentation can disperse as far away as 755 feet (230 m).

The grenade is olive drab body with a single yellow band at the top. Nomenclature and or lot number markings are in yellow.

Grenade, Hand, Frag, Delay, M67

WARNING: Although the killing radius of this fragmentation grenade is 16 feet (5 m) and the casualty-producing radius is 50 feet (15 m), fragmentation can disperse as far away as 755 feet (230 m).

The grenade has an olive drab body with a single-yellow band at the top. Markings are in yellow.

This is a training standard item used in both training and combat.


Grenade, Hand, Practice, M69

The M69 practice hand grenade simulates the M67 series of fragmentation hand grenades for training purposes. The grenade provides realistic training and familiarizes the soldier with the functioning and characteristics of the fragmentation hand grenade.

After a delay of 4 to 5 seconds, the M69 emits a small puff of white smoke and makes a loud popping noise. The grenade body can be used repeatedly by replacing the fuze assembly.

WARNING: Fuze fragments may exit the hole in the base of the grenade body and cause injuries.

The grenade is light blue with white markings. The safety lever of the fuze is light blue with black markings and a brown tip. The M69 grenade has a safety clip.

Type Classification Date: 1971. Unit cost of body: $5.62 (Fiscal Year 2000/2001).

Grenade, Hand, Smoke, Tng, M83

The M83 training grenade is deployed in a similar manner as the M8 series of service smoke grenades. It can be used to screen activities of small units and for ground-to-air signaling. The individual soldier in squad, company, and battalion units uses it. This item is urgently required to replace the existing M8 hexachloroethane (HC) filled munition.

The M83 hand grenade contains approximately one pound of environmentally acceptable smoke mixture. The smoke mixture is initiated by a pyrotechnic delay-igniting fuze. After initiation, there is a 3-second delay after which a dense smoke cloud of white smoke is produced.



Grenade, Hand, Non-Lethal (Stun), M84

The M84 diversionary/flash-bang stun hand grenade is designed to be thrown into a room (through an open door, a standard glass window, or other

opening) where it delivers a loud bang (170 to 180 decibels at 5 feet) and bright flash (1.5 to 2.5 million CP) sufficient to temporarily disorient personnel in the room.

WARNING: Do not practice "cook-off" with this grenade, since it has a short fuze delay time of 1.0 to 2.3 seconds.

CAUTION: Use stun grenades as field-expedient early warning devices only when in a combat environment.

Use of the M84 is not recommended for use in crowd control situations. Specialty teams, such as security response teams, and search teams may use this device effectively.

The body is a steel hexagon tube with 12 holes along the sides to allow for the emission of intense light and sound when the grenade is ignited. The M84 also has a secondary safety pin with a triangular pull ring.

The grenade is olive drab with white markings, with a pastel green band on body and a brown band on safety lever

Unit cost: $150 (Fiscal Year 2006/2007).

Grenade, Hand, Fragmentation, MK2

Obsolete. The MK2 is used to supplement small arms fire against the enemy in close combat. The grenade produces casualties by high-velocity projection of fragments.

WARNING: If the fuze is loose, do not try to tighten it. This could set off the granular TNT in the grenade.

The grenade has an olive drab body with a single yellow band, which indicates a high-explosive filler.

Grenade, Hand, Offensive, MK3A2

The MK3A2 offensive hand grenade, commonly referred to as the concussion grenade, is designed to produce casualties during close combat while minimizing danger to friendly personnel. The grenade is also used for concussion effects in enclosed areas, for blasting, and for demolition tasks. The shock waves (overpressure) produced by this grenade when used in enclosed areas are greater than those produced by the fragmentation grenade. It is, therefore, very effective against enemy soldiers located in bunkers, buildings, and fortified areas.

WARNING: The grenade has an effective casualty radius of 7 feet (2 m) in open areas, but secondary missiles and bits of fuze may be projected as far as 656 feet (200 m) from the detonation point.

The grenade is black with yellow markings around its middle. The MK3A2 may be issued with or without a safety clip.

Grenade, No. 5, Mark I

"Mills' Hand Grenade (Time)," "Mills grenade," "Mills bomb." Obsolete. WWI-era British grenade.

The body is cast iron, serated to provide fragments on detonation. A center piece is screwed into one end with separate recesses for the striker and the detonator. Mills grenades for use as rifle grenades (No. 23 Mills Rifle Grenade) must have solid, and not recessed, base plugs.

The striker is kept cocked against its spring by its head catching on the end of the striker lever when the latter is lying against the body of the grenade. The lever is retained in this position by the safety pin.

The igniter is a separate unit, consisting of cap, cap chamber, safety fuse, and detonator (No. 6, which is is 1 3/8 inches long, No. 8 which is 2 1/8 inches). The igniter is inserted into the grenade prior to use. Note that if a

fused grenade is not used, the igniter must be removed as soon as possible. Under no circumstances should a fused grenade be returned to store.

On withdrawal of the safety pin, the lever swings outward under the pull of the striker spring, thus releasing the striker which fires the cap. The safety fuse burns about five seconds and then fires the detonator.

Mills grenades were packed 12 in a wooden box, with a cylinder containing 12 igniters.

Dummy igniter sets were supplied for the Mills grenade. They were distinguishable from the live sets by a hole, about one-third of the diameter of the detonator in diameter, at the end of the detonator, and also by the cap having no central hole. Dummy Mills training grenades were painted white.

Grenade, Hand, Practice, Non-Lethal (Stun), XM102

The XM102 Reloadable Stun Practice Hand Grenade (RSPHG) is the reloadable trainer for the M84 Stun Hand Grenade. It offers realistic characteristics of the M84 to assist in the training of missions such as hostage rescue or capture of criminals, terrorists or other adversaries.

The XM102 consists of a XM240 reloadable cartridge (Unit Cost: $92, FY 2006/2007) and an inert blue body.

Unit cost: $140 (Fiscal Year 2006/2007).
