The unit was formed on 3 September 1939 as a 2nd Line Territorial Army Tank Brigade, but had very few tanks. On 28 May 1940, it was converted to the 2nd Motor Machine Gun Brigade in recognition of this lack of tanks, but converted back to an Army Tank Brigade on 10 December 1940. It was redesignated the 25th Tank Brigade on 1 June 1942.[1]
It fought in Tunisia under the British First Army and in the Italy as part of the British Eighth Army.
