I think devs should add a MI-24 Hind, along with that AAMs and ATGMs for the Mi-24 and Ah-64.
I think there should also be a couple new battle tank ideas being the T-90A, the Leapord 2A7, and the Challenger 3. (I have no idea where all these tanks would fit but probably on Coalition Forces because their army is made of different governments and resistance fighters.
