Later developments and possible replacement The Challenger 2 entered service with the Royal Scots Dragoon Guards, with the last delivered in 2002. After the Army 2020 restructuring, only three Challenger 2 Tank Regiments will remain: the Queen's Royal Hussars, the King's Royal Hussars and the Royal Tank Regiment, each of which is the tank regiment of an Armoured Infantry Brigade. A single Army Reserve regiment, The Royal Wessex Yeomanry, will provide reservist Challenger crews to the regular regiments.
