How did we win the ground war against the Germans with so technically inferior armor? It is a miracle.
1. We had more stuff.
2. We had air supremacy.
German tanks were usually reduced to acting as defensive tank destroyers, because if they moved into the open, they would be taken out by artillery, flanking tank assaults, or tactical air.
It is too bad for our troops that we didn't get Pershing tanks to Europe in 1944.
