The Service Test of Lightweight Body Armor, Basic Vest, T66-1, was conducted by the US Army Infantry Board from 6 January 1967 to 6 May 1967. The purpose of the test was to determine the suitability of the T66-1 vest for US army use to determine to what extent the T66-1 vest met the requirements of the LINCLOE QMR and to determine the suitability of the T66-1 vest for parachutists use and use with lowering devices. Four deficiencies and three shortcomings were found. The deficiencies were Lack of durability of the T66-1 vest, all sizes of the T66-1 vest exceed the weight limitations specified in LINCLOE QMR the T66-1 vest restricted head and body movement and breathing to a greater degree than the standard vest and consequently failed to improve, over the standard vest, the wearers ability to perform a combat related activity the T66-1 vest prevented parachutists from checking their entire canopies for malfunction or damage, thus creating a safety hazard to parachutists. The shortcomings were The inadequacy of the hand grenades inadequacy of the closure system on the bellows-type breast pockets for keeping the pockets closed and omission of instructions in the POMI for washing the T66-1 vest. The US Army INFANTRY Board concludes that the T66-1 vest is unsuitable for US Army use until correction of the deficiencies and as many shortcomings as practicable. The T66-1 vest is unsuitable for use by parachutists until correction of the deficiency noted in Subtest No. 4, Parachute and Rappelling. The T66-1 vest is suitable for use with lowering device.
