PRESELECTION TESTS.
Abstract
Men were being received at the Armored Replacement Training Center whose qualifications for the most part were not up to standards judged necessary for effective tank operation. This was regarded as a partial explanation of the frequency of vehicle failures, and of the habitual failure of many men to satisfactorily complete the course of training. The qualifications of tank crewmen established for this study were: Age - 30 or under (altenately 25 or under); AGCT - 90 or above (or alternately 80 or above); Height - 5 ft. 3 in. to 5 ft. 11 in. inclusive; Weight - 110 to 185 lbs. inclusive; Physical profile - 2-1-1-1-1-1 or above; Vision - acuity in each eye of at least 20/60; astigmatism in no more than 2 meridians of either eye; normal color vision; no glasses. On the basis of these qualifications, with the age limit at 30, only 17.1% of the 608 men examined were acceptable for training as armored troops. With the age limit placed at 25, as few as 7.8% were acceptable. However, lowering the AGCT standard to 80, while maintaining the age limit at 30, resulted in the acceptability of 24.6% of this increment. Psychologic inadequacy, night vision, recovery from glare, and identification of preferential eye were not tested because of limitations in time and equipment. (Author)
