It's a pretty good old school RTS set in the cold war. You have a limited pool of forces to draw from during the whole campaign (but this pool increases as you unlock new units with the "command stars" you earn for completing objectives). You get a steady supply of reinforcement-points from holding strategic locations on a map, and use these point to call in units from your force pool. Story is a bit lackluster and sometimes poorly translated from French, but the campaign missions are varied and challenging.
You do not control the facing of tanks and other vehicles, but the crews and infantry are intelligent enough that they will turn to face the enemy, retreat if they're being attacked by an enemy they can't see, and if you order them to move to a spot near woods or bushes they will seek cover. Controls are intuitive and graphics are smooth and very nice.
I have played a few ranked online games, but I'm still working on the single player campaign. Multiplayer seems well thought out and fun. There are hundreds of modeled units from the NATO and Warsaw Pact forces to play with.
