Item; Dropped Loads,

(1) Observrtion: An analysis conducted by tlie 213th Assault Support Helicopter Company indicates that 48 percent of the dropped loads are caused by rigging equipment failure,

(2) Evaluation; Aerial delivery slings are subject to varying clijnatic extremes in Vietnam which range from daily saturation during the monsoon season to intense heat and dust during the dry st-ason. These conditions serve to shorten the service life of rigging equip- ment. Two loop slings become unacceptable for CH-47 loads in a very short time when subjected to these extreme clinrtic conditions,

(3) Recommendr tions;

(a) All CH-47 londs be rigged with three loop slings or double two loop slings only.

(b) During the monsoon season, the service life of all sling equip- ment should be reduced from six (6) to three (3) months.

c. (C) Training.

Item; Dual Helrrat Fire Control System and Modified M-5 Sitting System.

(1) Observation; Both the dual hülmet fire control system and the modified M-5 flighting oystem were tested by the 11th Combat Aviation Battalion. The dual helmet fire control system consists of two helmets equipped with illuminated reticles, mechanical linteige and electronic connections (to include lead-angle compensator). This system is capable of firing the M-21 weapons system. The modified M-5 sighting system consists of a standard M-5 si^it into which a seven power monocular has been placed and affixed to a gyro-stabilized lens. This sight is cap- able of firing the M-5 weapons system.

(2) Evaluation; The dual helmet fire control system is a vast im- provement over the present M-6 sight. The du"! helmet sighting system with the lead-angle compensator is extremely accurate and allows either

pilot to engage tark'etBj therefore, tr.r.^etB which «^.le off the planned fir- ing axis mey be engaged much faster nnd vdth greater prob-.bility of achie- ving first round hits. The modified M-5 sight, vith its seven power mrgni- fication and the" lead angle compensator, permits tr.rgut detection rt an increased range. The gyro-stabilized lens eliminr.tes much of the "target bounce", pemitting greater accuracy« When attempting to firu off axis with the modified M-5 sight, the same llmitntiuns, mechanical stops and blocked vision problems are prevalent as in the current M-5 sight.

(3) Recommendations;

(a) All UH-1 gunships which are presontly eauipped with the M-6 sight be converted to the (kial helmet fire control system at the earliest pos- sible date.

(b) The modified M-5 sight does not Incorporate sufficient Improvements over the present system to recommend Its acceptance Into the Army inventory.

AVHGC-DST (13 Nov 68) 4th Ind SUBJECT: Operational Report of the 11th Ccnbat Aviation Battalion for

Period Ending 31 October 1968, RCS CSFOR-65 (Rl) (U)

HEADQUARTERS, UNITED STATES ARMT VIETNAM, APO San Francisco 96375 2 7 DEC 1368

TO: Coonander in Chief, United States Aragr, Pacific, ATTN: GPOP-DT, APO 96558

1. This headquarters has reviewed the Operational Report-Lessons Learned for the quarterly period ending 31 October 1968 from Headquarters, 11th Ccnbat Aviation Battalion.

2. Ccnmsnts follow:

a. Reference item concerning dropped loads, page 9, paragraph 2b; and 3d Indorsement, paragraph 2b: Concur. IM 55-450-11 and USAHV Regulation 725-7 instructions were written expressly for use of three loop slings; however, two loop slings may be used in lieu of three loop within weight limitations. This substitution is required since it will be March 1969 before USARV will receive all the three loop slings required. TK 55-540-11 lists very specific criteria for the etorage, inspection, and maintenance of air delivery slings. With the minimum precautions taken, slings will remain serviceable for six months.

b. Reference item concerning dual helmet fire control system and modified M-5 sighting system, page 9, paragraph 2c. Concur. This head- quarters forwarded these same reccnnendatlons in an evalration report of the Dual Helmet Sight and the Modified M-5 Sight on 3 Decker 1968.
