According to reliable reports, the tactical use of antitank weapons by German units operating on
rearguard missions, is as follows: First, the 88-mm dual-purpose guns fall
back, then the combat engineers, and the antitank guns last. Unless the attack is too
overpowering, the antitank units, before withdrawing, stand fast for a length of time
designated in orders. If the gun positions are undetected, antitank fire is opened only
at the last possible moment, since the German 50-mm guns are not effective
against General Grant (U.S. M3) and General Sherman (U.S. M4) tanks at long ranges. If the
gun positions are known to the enemy, long-range fire is employed.
