I was playing "South of Sword" as the British against the AI and getting my butt kicked. Read this thread about the mortars, restarted, moved my 3" mortars to the 3 houses toward the center and hid them behind the buildings. Put Company CO upstairs where he had decent observation of the area where the German armour is concentrated. No other infantry weapons except a few MG's were in firing range.
During the course of the game, my 4 mortars using indirect fire killed approx. 20 German armoured vehicles to include "open topped" AC's, HT's, Stugs, and Pz4's...and still had about 10 rounds apiece left to use on infantry. The mortars were the major killers of AT gun armed units, and I didn't commit my tanks until the mortars had greased most of the German AT gun armed units. Basically, my armor was only used to kill the leftover HT's and provide fire support for the infantry.
To say the least, this is pretty "gamey". As is, I'd take an onboard mortar firing indirect fire over a dedicated tank destroyer anyday, let alone a AT gun. The German units would move to escape, but the first round was usually a hit. Direct fire against a tank usually ineffective...no kills noted. I haven't graduated to PBEM games yet, but since the it's often "one shot, one kill", it'd probably be effective there as well.
