August 1944. Somehow Hitler is convinced that since his empire is being strained economically and broken militarily, in order to maximize AFV production he should drastically reduce tank production and increase assault gun/jagdpanzer production, because self-propelled guns are cheaper.
So the Panzer IV is put entirely out of production, and Stug IVs and Jagdpanzer IVs are built instead. Panther production is reduced slightly and a few more Jagdpanthers are produced. Meanwhile Tiger II production is cut in half to make room for more Jagdtigers.
What would happen next?
