Para can be dropped anywhere, but they can't reinforce anywhere like the first game. They need someone to plant a beacon for the plane act as Para's reinforcing point.
Good thing about that, Para reinforcing cost would no longer insane high. They can also reinforce from HQ and other HT thingy.
And no RR for them.
Rifles: Best basic infantry (again)
All US vehicle can be dismount and given to anyone capture it, you may give them to the Commies creating crazy combo or troll your teammate giving Sherman to the Germans.
The crew themselves can fight, cap, repair their own wheel.
Infrared Halftracks = Maphack Halftrack
KT = Fat Tiger, period
