I know my military history reasonably well, and WWII history in particular, and had no idea who Eberhard von Mackensen was. Weird list just on that.
Oh, and there is no doubt Guderian created the doctrine for combined arms built around tanks, mechanized infantry, self-propelled artillery, and close air support that came to be known as Blitzkrieg. No “said to have developed modern German tank strategies” about it, it is absolutely so. He owed a lot to a Brit named Fuller, but Guderian was able to get Hitler and the Wehrmacht to listen to him.
JFC’s a good one.
