How about this idea to get your troops on the ground, in hostile territory, in a hurry.
A personal Airbag Insertion system like the Pathfinder landing package.
With a radar or GPS(?) triggered deployment system, the airbag suit could safely be inflated at an altitude of 200 feet.
With a quick release system the airbags could be left as decoys or deflated to maintain an element of surprise. (If no one saw the troops bouncing all over the place)
