ummm apache's can be transported via aircraft, and is a humvee made out of tank parts ? ... your logic is flawed
more C&C like ? ... no as C&C renegade was made that way, so .....
if you wonna make it more like a C&C game why not have the player wait 1-5 mins (depending on the fire/defencive power) befor thay get the vehicle ... but that would be taking the piss would it not, the game would be over befor you got ya "order"
ohh yer and your aircraft might not make it to the bace (snipe snipe)
