Just one improve, because I've been really desappointed by it. Why antitank gun can't attack StuG ? Because it's called "Assault Gun" IG !?! o_O On wikipedia, it's said that "the combat tank [...] is a mobile weapon system consisting of a barrel mounted on an armoured car and tracked vehicle." And from the Larousse dictionnary "a tank comprises a chassis constitued by an armored crate and a caterpillar track. [...] The weaponry is GENERALLY carried by a turret with total rotation." NB all citations are translated from french, and the Larousse is the official french dictionnary. So I don't know why the StuG are not considered as tanks.
