The idea is not mine, and certainly not new. Just tried to put it into context with the capabilities of the other branches.

The Russians (Soviet's, that is) had/have a whole bunch of their "VDV" formations designed for just exactly that concept, that's what the BMP vehicle series was/is for. And the fact that they lost the Cold War doesn't change their quite sharp minds in military matters and their tendentially clearer conceptual thinking. And if you look into the late years of the German Wehrmacht, they were also thinking into that direction, with Ar232 and Me323.
