The game is categorized as RTS although its more RTT (Real-Time Tactical), the basic controls are like in other RTS games, you point and click your units to move and to attack enemy units.
But you don't build up bases, you have a limited amount of troops or you can buy a limited amount of troops in multiplayer to fight your opponent.
The game is also very realistic and offers you lots of opportunities to defeat your enemy. There is no big unit vs small unit = big unit wins. Winner is the best tactician of both, you can take out a superior German Kingtiger with a single soldier if you sneak along bushlines and throw a molotov cocktail on it's engine compartments. Or if you have a weaker tank, you can knock out the tracks of an enemies tank to surround him and to attack it at its weak spots.
And to make this really outstanding from all other RTS games out there, you can switch into the role of every unit you have and play it Action game wise. For example you can take the control of a tank and drive through buildings, shoot and aim for weakspots of enemies to smash them on your own. Though the view perspective is still bird eye so you don't loose your overview.
