The base unit here is the army, so you will not need to move and survey countless units. And the game is turn-based (one turn equals one week).
As the commander-in-chief, you will have to make historical strategic choices.
The game is quick to learn, hard to master
You can play the Axis forces, the USSR, or… both. Playing both at the same time will allow you to test unique historical scenarios or alternative histories of your own.
