Getting behind the other guy's infantry is very important.
it is a platoon tactic, performed within company operations. Not the classic breakthrough and pursuit to "roll up the line" of larger scale battles. The light mortar (2", 50mm and 60mm) is very handy for laying smoke on the the other guy, as well as keeping heads down on his machine gun units while I move closer, around or to better cover. also great for popping his guns. my general theory is this: Tanks against his infantry, AT against his tanks, infantry against his AT. not to be followed to the letter, or adhered to strictly-just a general guideline.
