The 19th Brigade is an Army Reserve brigade of the British Army. As the 19th Infantry Brigade it fought in the First and Second world wars. The brigade became 19 Light Brigade in 2005, and moved to Northern Ireland following the end of Operation Banner and "normalisation" of British military operations in the province. Following the 2010 Strategic Defence and Security Review (SDSR), the Brigade entered suspended animation in March 2013. As part of the Future Soldier reform the brigade was reactivated in 2022.
