Specialized units enjoy a higher combat proficiency than the standard for that unit, and provide a unique strategic advantage to the player throughout their campaign.
Such would include the Sturmtruppen and the Mark IV Tank, among others. The campaigns also provide a historical atmosphere by slowly expanding the player's unit roster over the course of the war based on the historical innovations of the featured armies regardless of affiliation, the player starts the game with limited options, and unlock new units and fire support with every battle they win, tanks being among the last and available to the British before the Germans. Regardless of game mode, the player is tasked with achieving victory in one of two ways: forcibly conquering the enemy's side of the battlefield, or killing off enough enemy units to deplete morale and force a surrender.
