Two prisoners from the 2?3d claim that theregiment's attack plan directed the 1st Battalionto make a frontal assault on the district headquartersand the 2d and 3d Battalions to attack the left andright sides. The purpose of the operation was tooverrun the compound and evacuate prisoners andequipment to the regimental headquarters about 15miles from Loc Ninh. According to previous reports,the 1st and 2d Battalions may have been the unitsthat had overrun the compound early on 29 October butwere forced to withdraw by Allied reaction forces.

a number of attacks occurred in 1st Corps on2 November. About 35 mortar rounds were fired atthe Vietnamese Navy base at Goa Viet in Quang TriProvince, and 25 rounds of lOS—mm howitzer firestruck a base manned by an ARVN artillery battalionnear Gio Linh.

The generals intend to let PresidentThieu and Vice President Ky run the government with-out interference and merely provide advice and guidancewhen requested or when some problem arises which affectsthe government's stability.some time how much Thieu will rely on the generals.Maj Gen Le Nguyen Khang, 3d Corps Commander, believesthat Ky has lost much prestige recently but does notthink that any anti—Ky movement is under way. Khangadmits that the military leadership has failed inmany respects over the past two years, especially ineliminating corruption,

t6:HMore Information on Soviet 122—mm Rocket in Vietnam

Initial examination of launch tubes for a Soviet122—mm spin—stabilised rocket captured recently inSouth Vietnam shows that they generally fit the des—cription obtained previously through prisoner inter-rogation. The tube is 8.2 feet long, weighs 44 pounds,and has an outside diameter of 126.5 millimeters andan inside diameter of 122.4 millimeters. It seemsto have been designed for a Soviet multiround launcher —-possibly a prototype of the 115-mm 40—round rocketlauncher —— and then modified for single-tube operation.Cyrillic markings were noted on an attachment forsecuring the single tube to a ground mount.

Although one has yet to be captured, a fairly de—tailed description of the ground mount for a 122-mmlauncher has been provided by a former gunner of a 122—mm rocket unit. He says that the mount consists of atripod with one leg forward and two aft. The mount isheld firmly in position by 4x3—inch pads fastened tothe end of each leg. The distance from the front legto the rear ones is about Six feet -- that between rearlegs is about 2.5 feet. This description and the measure-ments generally conform to the size, shape, and locationof the three probable ground wells in the forward endof excavations sighted in northeastern Cambodia. Theseexcavations -— believed to be training positions --would probably accommodate a 10— to 14-man crew, alsoreferred to by the former gunner. The most likelycandidate for this type of excavation is the 122-mm spin—stabiliaed rocket.

a cache of 122—mm rocket components was recentlydiscovered along with a document that describes a”spoiler ring" packed with the rocket—propellant sections.The ring was said to have a diameter of 112 millimetersand to have been attached to a groove immediately behindthe fuse. Its purpose was to create drag so that therocket could be fired at ranges between 3,200 and 5,500yards, thereby permitting targets to be engaged thatmight be masked by terrain obstacles atlnormal firingelevations. The ring might also allow the weapon to beemployed either from concealed firing positions near thetarget or from well—prepared positions farther away.This is the first known use of such a device on Soviet

rockets, and similar types of Spoilers could beused on existing rocket systems for firing atintermediate ranges. -LSEGRH¥%

NE I More MIGs May Have Deployed to China

North Vietnam's MIG fighter force has beenfurther reduced. Fa13fimfl) leastthree probable MIG—15/l7s and one probable IG-21flew from Gia Lam to Communist China —- probablyto Nanning —— on 3 November. This reduces thetotal of estimated operational jet fighters inNorth Vietnam one MIG—17/l7 and three MIG—2ls.‘

fiéi High—Level Chan es in North Vietnamese Governmenttr

North Vietnam has announced a number ofpersonnel changes in the government, primarilyinvolving those in the economic field. Politburomember Le Thanh Nghi was replaced as Minister ofHeavy Industry by Nguyen Huu Mai who has been incharge of Communications and Transport since 1955.Nghi is expected to continue to wield considerableinfluence on economic matters and will probablyremain North Vietnam‘s chief aid negotiator.

Other personnel shifted were Hoang An, whorelinquished his post as Minister of Agricultureto Hoang Quoc Thinh. Some of the other newlyappointed officials may have been serving in SouthVietnam. These include Chairman of the State PriceCommittee Do Muoi and Col Nguyen Dinh Tung, who wasnamed President of the Central Military Court andVice Premier of the Supreme People’s Court.

The most unusual shift was the appointment ofNguyen Con, Chairman of the State Planning Commission,to the post of Vice Premier. There is nothing inCon's background or present duties that single himout for elevation to such a position. His appoint—ment brings to seven the number of vice premiers inthe regime. Five of them are members of the Politburo,including Defense Minister Giap and Foreign MinisterTrinh. 4SE€RE¥5ii-ifliiifii-flififlifli
