Thats in part because Hitler sacked Heinrici, and then brought him back only at the very last minute.

In WW II, a high degree of German military professionalism and considerable tactical and operational competence could not overcome gross strategic miscalculations and failures and a disparity of forces that eventually became disabling. In addition, although Germany produced some excellent weapons in WW II, due to her autocratic system, her overall production effort and military system were riddled with corruption, inefficiency, waste, and missed opportunities that often failed to meet even urgent combat needs.

Does this parallel Ukraine's circumstances against Russia? Not really. Russia's autocratic system today is closer to Nazi Germany or Mussolini's Italy than Ukraine's admittedly imperfect democracy.
