Hah, I wouldn’t have believed you about the mortars vs tanks thing had I not used them so effectively last night. Well, “it”, since I only had one. Two Panzers and a brumbar had isolated a Red Devil Cpt., a Garand, a Bazooka, and a Mortar, cutting them off from the main body of the force. The bazooka couldn’t get to them without crossing open ground. So the mortar sat behind the hill while the RDC was forward observer (we use that house rule). The Brumbar was taken out by a flanking Sherman, but the mortar actually damaged one of the panzers, making it easier for help to take one of them out (the other one got bogged down by a slew of reinforcements).
So yea, I’ll never underestimate mortars ever again.
