The Vickers 6-ton tank or Vickers Mark E, also known as the "Six-tonner", was a British light tank designed in 1928 in a private project at Vickers. Though not adopted by the British Army, it was picked up by several other armed forces, and licensed by the Soviet Union as the T-26. It was also the direct predecessor of the Polish 7TP tank.
