As part of the Delivering Security in a Changing World review in 2003, it was announced that the brigade was to become a 'Light' formation. The Brigade deployed on Operation Telic 2 between May and November 2003 taking over from 7 Armoured Brigade. The brigade became 19 Light Brigade as of 1 January 2005, and deployed to Iraq on Operation Telic 9 (November 2006 – May 2007) for an unusually long 7-month tour before handing over to 1 Mechanised Brigade and returning to Catterick. It then began moving to Northern Ireland following the end of Operation Banner and "normalisation" of British military operations in the province.
