Compared to our Germans, they were. They spent years getting for war, while our guys learned on the fly. And we kicked their ass.
Our Germans you mean like Patton? What percentage of our 12 million men under arms were German-Americans?
The cream of the Germany Army and by far the most casualties were suffered at the hands of the Soviets. The greatest battle in terms of size, casualties, and significance was the Battle of Kursk, which dwarfed D-Day. The outnumbered German Army was chewed up by the Soviets who suffered over 20 million casualties during WWII. We didn't kick the German's ass, the Soviets did.
