In the assessment of wind effects on tank projectiles, several interesting facts were noted. For the heavier projectile, the weighting factor curve for the longer range became somewhat linear whereas for the shorter 1500 m range, most of the wind weight was in the first 500 meters. For the lightweight high-velocity projectile, a nonlinear weight curve was present for all the ranges. Against a 3- by 3-m upright type target, the cross miss-distance dominated for the heavier projectile for all target ranges. However, as the target range increased the vertical and range wind displacements became significant. For the same type target and the high-velocity lighter projectile, the cross wind displacement again dominated the range wind displacement. However, the vertical wind displacement became approximately as large as the average crosswind displacement. The range wind appeared to have little effect on the accuracy of the high-velocity shell.
