I confess that I came with the idea of this thread after reading about Adna Chaffee Jr. because of a strategy game. In OTL he was not able to fight in WWII as he died in 1941, but what if he did? In Germany August Von Mackensen died in 1945 and I sure that Britain and France had old guard generals, veterans of WWI or even earlier conflicts that were alive at the time of WWII but didn't fought either for old age or health concerns. With the introduction over I ask: Which old guard generals could have fought in WWII? Maybe by living more or by having a better health at the time of the war?
