From the first landships of the Great War to the massive armor-battles of Prokhorovka and El-Alamein - the introduction of the tank to the battlefield had changed warfare forever. Impregnable to small-arms fire, they crushed barbed-wire and field fortifications underneath their tracks, paving the way for the infantry's advance. In independent formations they surged forward at the head of the offensive, outmaneuvering the enemy's defenses and wreaking havoc in their lines. From the Mark V to the T-34, from the Tiger to the Centurion, - the evolution of armor is the history of Steel Commanders.
