Also a factor in Germany’s defeat was the reality that German tank crews after July-August 1944 were not as well trained. Even in a superior tank like the Tiger or Panther poorly trained crews were no match for experienced American crews. A classic of this was the Battle of Arracourt in late September 1944 where American tankers won a lopsided victory over a German tank force consisting mostly of Panthers.
Yup. Same as with Japanese pilots. Towards end game, the best were mostly dead.
