No it doesn't. I was a member of a virtual OPFOR unit which specifically used the playable Russian vehicles in that simulation in both cooperative play and H2H battles. The idea was to test and use old Soviet armor doctrine for fun and learning, see if we can beat those guys who constantly harped about how great and god-like the western vehicles were. We learned quite a bit about Russian tactics and developed a great respect for their operational and tactical thinking. IIRC we won at least 50% of our games in H2H so it was no one sided win on the NATO side.
Below is a link to an old YouTube video of one of the H2H online campaigns run a couple of years back. The campaign was something like 8 weeks with two missions per week, first being a recon type mission to determine where start lines were in the big mission later in the week.
The video below is one from the perspective of a guy who played the NATO side. I was the guy opposite him running a Russian company plus of BMP-2s. He is shooting at me. We used coordination, smoke and HE fire to suppress while assaulting his positions and utilizing terrain to mask our approaches. I learned you adapt your tactics to your terrain and weapon systems. If you do it properly, you win. If you don't, you lose. This same principle applies to the Combat Mission series as well. We (The Russian Side) won this campaign by the way.
