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.[2] 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.[3] It was developed as a response to British tanks. Although the A7V is generally considered to be better designed compared to its counterparts, it struggled to procure high production numbers due to its relative complexity and high cost.[4][5][6]
