There is probably not much new in military strategy.
I always felt that Patton learned much from Confederate Guerrilla leader John Mosby who was often a house guest of the Pattons. Patton would ride with Mosby around their ranch and learn lessons of war. George JR. was only a boy at the time but already determined to be a general.
One of Patton’s Grandfathers was a Confederate General and the other a Confederate Colonel.
“There is probably not much new in military strategy”
Depends on how broadly you define it. There are all sorts of tactical revolutions given changing technology. Blitzkrieg is essentially a mixture of various new tactics designed to exploit tanks and airplanes, which were designed to get around machine guns and heavy ground artillery. But it also was a new strategic vision that reoriented us away from the defensive nature of WWI.
