The 7th Armoured Brigade was an armoured brigade formation of the British Army. The brigade is also known as the "Desert Rats", a nickname formerly held by the 7th Armoured Division, of which the brigade formed a part during the Second World War until late 1941.

The 7th Armoured Division was an armoured division of the British Army. It was formed as the Mobile Division (Egypt) on 27 September 1938, after increased tensions between Britain and the Axis powers. This was part of an effort to reinforce and maintain the British strategic presence in Egypt to defend the Suez Canal, which was seen as vital to the British Empire's interests. In February 1940, the formation was renamed as the 7th Armoured Division. During its early years, the jerboa was adopted as the mascot and divisional insignia giving rise to the nickname Desert Rats.
