	The 30th Armoured Brigade was created on 27 December 1940 as part of Northern Command. It was initially formed from the 2nd Battalion, The Queen's Westminsters, a motorized infantry unit, which was joined by a cavalry unit, the 23rd Hussars, three days later, on 30 December. Just over a week later, on 8 January 1941, the 23rd Hussars were replaced by the 22nd Dragoons, and on 28 January the brigade was transferred to Western Command.
