The 28th Armoured Brigade was a regular British Army formation in World War II. In 1939, it started off as the 2nd Armoured Reconnaissance Brigade. After Dunkirk, with the lack of Armoured vehicles, it was converted into the 3rd Motor Machine Gun Brigade on 1 December 1940. As more equipment became available, it was eventually converted into the 28th Armoured and served in the United Kingdom throughout the war, under the command of the 9th Armoured Division. It was disbanded on 21 August 1944 without having seen active service as a unit.
