The reviewers concluded that: (1) Deficiency identification was conducted in a logical, systematic manner; and resulted in useful hardware and software improvements; (2) Thirty hours of U-COFT sustainment training produced substantial average gains in the proficiency of a test group comprising five TC- gunner pairs; (3) Forty hours of U-COFT transition training with another five TC-gunner pairs produced average exit-level scores equal to or greater than those obtained by the sustainment pairs. Proficiency gains for the transition group, while probably substantial, could not be estimated accurately, because entry-level proficiency scores were not obtained; (4) Proficiency gains in target-acquisition time on the U-COFT were underestimated by at least one-third in the V/V report; (5) Substantial gains were found in percents of targets acquired, engaged, hit, and killed by the sustainment and transition groups. The gains resulted from improvements in acquisition time, engagement time, and first round hits, which in turn allowed time to scan, acquire, and engage available second and third targets; and (6) Nine hours of U-COFT training and testing produced statistically significant improvements between pretest and posttest scores of eight Canadian Armor Trophy (CAT) TC-gunner pairs on several measures of gunnery proficiency.
