On the question of moving and deploying AT assets in the attack.
The following document, published by the Oberkommando des Heeres (German army high command) 1 March 1942, details the experiences gained on the Eastern Front. Anti tank combat
42.) Employment
The appearance of enemy tanks must be reported by all parts of the spotting- and guard sections by the fastest possible means to warn the troops.
Due to their immobility, the 5 cm Pak must be placed into position, in accordance with the anti-tank plan, at an early stage. Because of their greater mobility, the 3,7 cm Pakcan be kept ready behind cover, or concealed near already prepared positions.
Positions must be set up around bushes, hedges, etc., maintaining good traversability, but above all good camouflage. Foxholes must be laid out, without creating earth mounds, for the gunners and ammunition. Laying out mines around the position prevents tanks from overrunning the position.
