4th Light Brigade Combat Team

Brigade formation of the British Army

4th Light Brigade Combat Team, previously known as 4th Infantry Brigade and Headquarters North East, and before that as 4th Mechanized Brigade and before that 4th Armoured Brigade is a brigade formation of the British Army, currently based in Catterick, North Yorkshire as part of 1st (United Kingdom) Division. The brigade, now known as the 'Black Rats', was formed in 1939 and fought in the Second World War in the Western Desert Campaign in North Africa. The Black Rats were subsequently involved in the invasion of Sicily and fighting in Italy before taking part in the Battle of Normandy and the advance through Belgium, Holland and into Germany. More recently, the Brigade took part in the First Gulf War and completed a number of tours to the Balkans during the 1990s. The Black Rats have also since deployed twice to Iraq and twice to Afghanistan as the lead formation.

In September 1939, at the start of the Second World War this brigade changed its title from Heavy Armoured Brigade (Egypt) to 4th Armoured Brigade. On 27 July 1941, it handed over its units to the 1st Army Tank Brigade and received new units based in Egypt. It was reformed again when the HQ arrived in Sicily and it took control of new units there. The 4th Armoured Brigade saw service in the North African Campaign, the Allied invasion of Sicily, the Italian Campaign and in North western Europe. Although it served under many different formations it was most famous as part of the 7th Armoured Division, the "Desert Rats". The 4th Armoured Brigade was the first to cross the Rhine into Germany.

The brigade spent many years in Germany as part of the British Army of the Rhine. The brigade was one of two "square" brigades assigned to 2nd Division when it converted into an armoured formation in 1976. After being briefly converted to "Task Force Charlie" in the late 1970s, the brigade was reinstated in 1981, assigned to 3rd Armoured Division and was based at York Barracks in Münster. The Brigade deployed to the First Gulf War on Operation Granby in 1990/91 and was involved in the liberation of Kuwait. It moved to Quebec Barracks at Osnabrück in 1993 to replace 12th Armoured Brigade as part of 1st (UK) Armoured Division.

4th Armoured Brigade deployed to Bosnia in October 1995 as UNPROFOR HQ Sector South West and subsequently as the leading UK element of the NATO Implementation Force (IFOR). The Black Rats have since deployed twice to Iraq and twice to Afghanistan, first on Operation Herrick 12 in 2010; and again in October 2012 for Operation Herrick 17, during which it was working in support of the Afghan Army's 3/215 Brigade and elements of the Afghan National Police.
