Can we have the Panzer III next?
The Panzer III served as Germany's main tank from 1940 to early-mid 1942, when it began to serve alongside upgunned Panzer IV's as what we would now call a battle tank.
It lead the charge through the low-countries and France, fought admirably in North Afrika, and spear-headed the advance into Russia. The last major offensive where the Panzer III was present in large numbers was Operation Citadel, aka the battle of Kursk in July 1943.
Why should we get the Panzer III? Well, several reasons. 1) its historical significance as the tank that led the Blitzkrieg from 1940 to 1943. 2) it would give us most of the components (both visual and in the driving model) needed for a StuG III. 3) the 50mm L'60 is already in the game, in the form of the BK 5 on the Me 410.
I propose we add:
Panzer III Ausf. F: 30mm armor on the front hull, and all around on the turret, 37mm L'45 or 50mm L'42.
Panzer III Ausf. J: 50mm armor on the hull front, 30mm, 50mm L'42 or 50mm L'60
Panzer III Ausf. L: 50mm + 20mm on the hull and gun mantle, 57mm on the turret front. 50mm L'60
These three variants would give us good coverage all the way from 1939 to 1943. They would also give us the chassis to add the Stug III Ausf. A with 50mm armor an the 75mm L'24, the Ausf F with 50mm armor and the 75mm L'43, and the Ausf G with 80mm armor and the 75mm L'48.
