Armoured Car Regiments were reconnaissance units employed by the British Army during the 20th century. The primary equipment of these units was the armoured car with many different types of armoured cars serving in the regiments during the Second World War and the Cold War. An armoured car regiment typically numbered several hundred men and several tens of armoured cars. By the end of the 20th century, armoured cars as front-line reconnaissance vehicles had been supplanted by tracked vehicles in the British Army and the surviving regiments converted to other organisational forms.
