In 1992, the 4th/7th Royal Dragoon Guards and the 5th Royal Inniskilling Dragoon Guards were amalgamated into a single Regiment. This makes the Regiment the successor to four cavalry regiments - the 4th, 5th and 7th Dragoon Guards and the 6th (Inniskilling) Dragoon Guards.
Each of these four regiments now equates to a squadron in The Royal Dragoon Guards, with ‘A’ Squadron perpetuating the traditions of the 4th, ‘B’ Squadron continuing the 7th, ‘C’ Squadron representing the 6th and ‘D’ Squadron the 5th. The regiment also has a fifth, Headquarters Squadron.
The Royal Dragoon Guards operates Challenger 2 main battle tanks as well as carrying out close reconnaissance in Scimitar armoured vehicles. Although its headquarters is in Catterick and its main recruiting ground is Yorkshire, it also recruits in Northern Ireland, with which all its regimental predecessors have links. The regiment has also inherited the image of Enniskillen Castle on its cap badge from the 5th Royal Inniskillings.
Three of the Regiment’s squadrons deployed to Northern Ireland in 1996. A further squadron of the Regiment was posted to Bosnia in 1997, while the Regiment as a whole deployed to Iraq in 2004 and 2007. Recent deployments have been to Afghanistan during April 2010 and October 2011.
