No argument from me, at least as far as new divisions.
I like an idea that I remember reading in Patton's "War as I knew it," in which he recommended a parachute regiment for each Army, for quick-grab operations, like a bridge in the enemy rear. With the advent of helicopters, I think some kind of air-assault unit on call for a corps or army commander would be a handy force-multiplier.
I point out that the Soviets apparently agreed, and there was an air-assault brigade assigned to each Front, and another for the Shock Army/Tank Armies that were supposed to be the breakthrough and exploitation forces. These were in addition to the airborne-mechanized divisions held in strategic reserve.
For me, I guess for the US, I would have liked to make that a Ranger unit (company/battalion) semi-attached to a corps' helicopter brigade. It could be dropped or choppered to some location really quickly. If not Rangers, then consider them light dragoons, and we are back to the cavalry theme of this thread.
