Abstract : The GUNNERY project was designed to gather preliminary data leading to an understanding of the relative effects of a subcaliber training method and of the ATP method on 90mm gunnery proficiency. Accordingly, the subjects, two groups of 40 men each from an Armor training company (ATP 17-600), were given training which differed only in the 90mm firing phase. The Control Group was given the ATP, including 37 90mm rounds and 480 subcaliber rounds. The Subcaliber Group received the normal 480 subcaliber rounds, one 90mm round (Table VIII), and 99 substitute rounds on the .30 caliber coaxial machine gun (M47 tanks). A secondary purpose grew out of the need to develop a satisfactory experimental test of 90mm firing proficiency. This test (taken by both groups during the 10th week of cycle) involved firing 12 rounds, 6 for zeroing, and 6 for checking zero, at 1500 yards known distance. The results of the test are the following; (1) The level of trainee performance was about 55% hits after zeroing, as compared to over 90% for expert gunners. (2) There was no difference between the ATP group and the subcaliber group on the experimental firing test. (3) It is possible that the results of additional tests given to trainee groups after additional research and training, may indicate that extensive subcaliber training would lead to a reduction in the cost of training ammunition without affecting present levels of performance.
