When General Bernard Montgomery commanded the division during World War II, the insignia was the 'pattern of three' - a black triangle trisected by an inverted red triangle.
The British 3rd Division is sometimes referred to as the 'Iron Division,' a nickname earned during the bitter fighting of 1916. See British 3rd Division (World War I) for the division's World War I history.
Currently the 3rd Division is the only division at continual operational readiness in the United Kingdom and comprises three mechanised brigades; the 1st, 12th and 19th.
3rd Division today serves as one of the British Army's two operational ready divisions (the other being British 1st Armoured Division in Germany). Under the divisional command are three ready brigades:
1 Mechanised Brigade
12 Mechanised Brigade
19 Light Brigade
In April 2007, 52 Infantry Brigade will be transferred to the operational command of 3 Division.
