Tank Gun Trajectories

The U.S. WWII field manual FM 17-12: Tank Gunnery illustrated representative trajectories of the 37-mm, 75-mm, and 76-mm guns. Low velocity guns with more highly curved trajectories require very accurate range estimation. As shown in the figures below, even small errors in range estimation reduce the effectiveness of the opening shot and increase the number of rounds required to achieve a hit.
