yeah you can get away with a lot more on 726, e.g. PzKpfw IV Ausf. F2 had it from the moment it spawned (Mareth Line) to the end of the game without getting killed, it had run out of ammo a long time back but I still chose to charge a crusader that shit itself and reversed away ending the game.
726 majority are eighter to stupid to be considered real adversaries or they just don't care that they die - like ceatures of habit, one guy goes for the pak gun, I shoot him, he respawns - instead of even looking for me, he goes for the pak gun... I let him get on it, hear the cunk click of a shell now loaded... shoot him, "Paks closed!" He spawns again, now even the dumbest player would think to look and see where the last two shots came from, not this guy, he's off to the pak gun again... pweoowmm! He's dead. He spawn again, now he's alert, scanning the horizon for... a pak gun, off he goes again, TeuFFF! He's shot again.
