A7V

The A7V was a tank introduced by Germany at the end of World War I in 1918. The name is probably derived from the "Allgemeines Kriegsdepartement 7 Abteilung Verkehrswesen" (General War Department 7, Branch Transportation), although some theorize that Hauptmann Joseph Vollmer gave the V to the name. In German the tank was called "Sturmpanzer-Kraftwagen" (translating roughly as 'Storm/assault armoured motorized vehicle'). There were 100 ordered for the spring of 1918, but only 20 were delivered. They saw action from March to October that year, and were the only tanks produced by Germany in WWI.
The tank had 20 mm of steel plate at the sides and 30mm at the front; however the steel was not hardened armor plate, which reduced its effectiveness. It was thick enough enough to stop machine gun and rifle fire, but not larger calibres. This offered protection comparable to the thinner armor of other tanks of the period, which used hardened steel.
The top speed was about 15 km/h on roads and 5 km/h across country. Power came from two Daimler 4-cylinder engines delivering 100 hp (74 kW) each. The tank was over 7 metres long and 3 metres wide. The height varied up to 3 metres.
The A7V was armed with six 7.9 mm MG08/15 machine guns and a 5.7 cm cannon mounted at the front. The crew normally consisted of up to 16 soldiers and two officers. It was as slow as other tanks of the day, but had very poor off-road capability and was prone to getting stuck. The large overhang at the front and low ground clearance meant trenches or very muddy areas were impassable. However, on open terrain it could be used to some success and offered more firepower than the armoured cars that were available.

Combat History
The A7V was first used in combat on March 21, 1918. It was deployed north of the St.Quentin Canal. The A7V's helped stop a minor British breakthrough in the area, but otherwise saw little combat that day.
The first tank vs tank fight in history took place on the April 24, 1918 when four A7V's (including chassis number 561, known as "Nixe") taking part in an attack with infantry incidentally met three Mark IVs ( two Female machine gun tanks and one Male with 6 pounder guns) near Villers-Bretonneux. During the battle tanks on both sides were damaged. According to the lead tank commander, 2nd Lt F. Mitchell, the machine gun armed Female Mk IV's, unable to damage the A7V's with their own MG's, fell back. He then attacked the lead German tank with the 6 pounders (2.7 kg) of his own tank knocking it out, and killing five of the crew. The rest of the crew of that tank bailed out. He then went on to rout some infantry with case shot. Some Whippet tanks also engaged the infantry. The two remaining A7V's in turn withdrew. The British tank lost a track towards the end from a mortar shell and was abandoned. The A7V was later recovered by German forces.
All the A7V's available had been put into action that day with limited results; two toppled over into holes, some encountered engine or armament troubles. After a counterattack three ended up in Allied hands. One was unusable and scrapped, one used for shell testing by the French and the third taken by the Australians.
The A7V was not considered a success and other designs were planned by Germany, however the end of the war meant none of the other tanks in development, or planned ones, would be finished (such as the Oberschlesien, K-Wagen, and LK series). The A7V's were last used in October 1918; a number were scrapped before the war ended in November.
The extremely limited production of twenty made their contribution very limited, and most tanks (less then a hundred) that were fielded by Germany in WWI were captured French or British tanks (Beutepanzer), who together had produced and used thousands of them. The French alone had produced over 3600 of their FT-17, the most produced tank of WWI, and the British over 2500 of their Mark I to V.
The captured A7V Mephisto is in the Queensland Museum in Brisbane, Australia and a replica of the A7V Wotan is in the German tank museum at Munster.
