The 1957 Defence White Paper announced the end of National Service, resulting in a number of reductions and changes across the Armed Forces. Part of this restructuring saw the disbandment of the 6th Armoured Division in April 1958. The Brigade survived as the new 20th Armoured Brigade Group, initially under the command of the 4th Infantry Division, and moved to Hobart Barracks, Detmold. It assumed the insignia of the old Division – the "Iron Fist" symbol that it wears to this day.
