The Sturmpanzerwagen A7V was a heavy tank introduced by Germany in 1918 during World War I. One hundred chassis were ordered in early 1917, ten to be finished as fighting vehicles with armoured bodies, and the remainder as Überlandwagen cargo carriers. The number to be armoured was later increased to 20. They were used in action from March to October 1918, and were the only tanks produced by Germany in World War I to be used in combat, as well as being the first operational German tank.
Although various German armoured vehicle proposals were shown a modest amount of support early in the war, enthusiasm among German high command was low and they were given little funding and attention. The sudden appearance of the British Mark series of tanks causing panic amongst the German infantry led this to be reconsidered however, and development on the German tank program began.
