I say we need more Russian vehicles. How about a BTR-80 or MT-LB? More Russian guns, AK-101 or RPG-7, and since BI aren't keeping to the 1985 setting (G-36, HMMWV etc) Russia should get Mi-28 or KA-50.
It would be nice to see some faster boats aswell. How about those little speed boat things used by special forces?
Amphibious assaults are quite difficult to do, so a proper LST (one that can beach it self) that can offload tanks would be good!
