So the purpose of fortified buildings is to protect infantry from being shelled by tanks This kind of fails when all of your "walls" and their "towers" @ each end have HUGE gaping holes in them from every direction It's already bad enough that any tank can solo a base turret while farming free kills from anybody trying to repair it. With the HE rounds you can shoot in the middle of the tower and kill anybody standing on the bottom floor as well http://www.castlesandmanorhouses.com/architecture.htm ^ a pretty good overview of everything your bases are missing.
