What about US paras? also, I know the Japanese had a DC-3, did they use it for airborne ops?
I vouched for British paras because of them being the best airborn troops in the world (then and now).

Otherwise, I matched the troops with the vehicle.
The Japanese used a version of the DC-2, iirc. Very close to the DC-3 (close enouhg for HTC to allow a skn), but not exact.
