Super niche nitpick: the photo is not of a tank. That appears to be a StuG III, which is not a tank. There is no turret, the gun is just fixed in the hull, with a couple degrees of freedom. Originally intended as a sort of mobile fire support for infantry, eventually got some anti-tank capability. They were not part of the Panzercorps by the Wehrmacht, who saw it as a specialized form of artillery.
