Factors Affecting Efficiency of Boresighting and Zeroing Performance in the M60Al Tank

摘要

In support of the US Army Armor School's training effectiveness analysis of the M60A1 tank, an attempt was made to identify factors in standard Armor training that may influence the number of rounds used to zero the tank main gun. Rounds to zero is a measure of efficiency in boresighting (visually aligning gun tube and sight) and in zeroing (correcting the aiming point by observation of actual hits). In a scheduled field exercise, 34 M60A1 tank crews filled in questionnaires on their knowledge of the principles and procedures of boresighting and zeroing, their perceptions of gunnery outcomes, and their experience. Afterward, data collectors observed and recorded the boresighting and zeroing exercises and results. Five factos were assessed in relation to number of rounds to zero: gun tube life, as determined from the tank logbooks; and the tank commanders' and gunners' experience, knowledge of procedures, knowledge of principles, and expectations of results.
