Uh, Are you looking for officers or particular U.S. Generals?
If you are looking for Lt., Captains, Majors, Colonels, I think there are plenty of choices out there.
If you are looking for Eisenhower, Patton, Clark, Bradley, Marshall, MacArthur, etc. you will have limited luck.
On the losing end of a wishbone,
and I won't pretend not to mind.
