Can't play as RU in solo/co-op

Everytime I try to play solo/co-op i load into US side. I like using the vehicles on both sides and practicing with all vehicles and not being able to play as the Russians side is disheartening. 

In the past some maps were RU sided and you'd play as them but not anymore. I've tested every map on conquest solo/co-op and everytime I load in I'm on US side. 

It would be nice if you could choose sides or it be a 50/50 chance on what side you get but now I'm always playing as the US. The hokum is my favorite chopper in that game too so it's a little more disappointing than usual.
