The developers decided that strategy would play a large part in the game, with no compromises being made and that the 'war model' would appear as realistic and natural as possible. Five types of ground forces, as well as sea forces, communications emplacements and factories appear in the game, and all interact with each other in ways that affect gameplay. Factories, for example, supply the military hardware and if destroyed will result in a gradual depletion of forces, since tanks and ships are destroyed but not replaced.
