They could always have delayed the DDAY invasions to 1945 so as to equip the Allied Armies with Pershings & Centurions!

I'm sure that the Wermacht would have given their left..... to have enough M4's to fully equip their Armoured units and have a solid reserve.

They would have found the right tactics to use.....
