The Royal Armoured Corps (RAC) is currently a collection of ten regular regiments, mostly converted from old horse cavalry regiments, and four Yeomanry regiments of the Territorial Army. It provides the armour capability of the British Army, with vehicles such as the Challenger 2 Tank and the Scimitar Reconnaissance Vehicle.

The RAC was created on 4 April 1939, just before World War II started, by combining the cavalry wing (cavalry units that had mechanised), and the Royal Tank Corps (which was thereupon renamed the Royal Tank Regiment within the new corps). As the war went on, many other units became mechanised and joined this corps. In 1944, the RAC absorbed the Reconnaissance Corps.
