RESULTS OF EMPLOYING A MODIFIED RETICLE DESIGNED TO ASSIST THE GUNNER IN COMPENSATING FOR TRUNNION CANT IN TANKS

Abstract

The effects of trunnion cant are significant when firing ammunition with muzzle velocities of 2500 fps or lower. This paper presents the conduct and analysis of data resulting from an experiment (conducted at Ft Stewart, Ga., during the period 23 June-4 July 1963) designed to evaluate the effectiveness of a modified reticle and to assist the gunner in compensating for the effects of trunnion cant. The use of ballistics computers that automatically correct for the effects of trunnion cant is the most satisfactory solution. The data presented show that cant is an important source of gunnery error, and that employment of a modified reticle as an interim measure to assist the gunner in compensating for cant results in increased accuracy of fire.
