The FV4101 Charioteer was a post-war armoured fighting vehicle of the British Army. The vehicle was produced in the 1950's to up-gun units of the Royal Armoured Corps continuing to use the Cromwell medium tank during the early phases of the Cold War. The vehicle was a modified Cromwell, with a more powerful gun installed in a lightly armored turret. All was mounted at a Cromwell chassis. The Charioteer was actually not used very much by the British army, but in other countries this tank saw more extensive action. It saw combat overseas by users in Europe and the Middle East, but most action conflicts of the Charioteer were in the Middle East. There were a total of 442 vehicles built.
