The A7V was first germans first tank, it had a crew of up to 18 and could do about 9mph flat out. It was armed with 6 machine guns and a 57mm gun at the front. It had a poor off road performance and only 20 were built, this meant that most tanks being used by the germans were captured british ones with a repaint and new markings. This replica was built on a lengthened tractor chassis and is driven from the back via a couple of cameras. The tank it reperesents "Schnuck" was captured in 1918 put on exhibition in britain and later scrapped. Cheers to the Tank Museum for linking this video on their website.
