I'm currently playing Silver Lions, and it seems that primary MBT for '85 is... T-10M! I've encountered them in two missions.
I havent't finished the campaign yet, but it's hind of strange to see tanks that should be in museums, lading attacks on NATO lines...

Only modern tank i've seen so far was Czech T-72. (I'm not counting some T-62s in one of the missions)
So i have to ask - are these T-10s placed for purpose, or is it just a bug? I'm using standart russian oob, no modifications.
