During the roughly three decades of "The Troubles" in Northern Ireland, the barracks served as the home base for battalions rotating through the province, especially those on a two-year "accompanied" tour with their families. A wide variety of facilities are available for soldiers to use off duty, including a swimming pool, squash courts, saunas, bars and a gymnasium.
Palace Barracks has been the Regimental Headquarters of the Royal Irish Regiment since 2008 and the home base of several squadrons of the 152 (North Irish) Regiment RLC. In March 2010, it was the site of a bombing, one of several attacks carried out by "hardline Republicans" in 2010; other attacks included the Newry car bombing. Since 2014 it has been the base for the Royal Scots Borderers, 1st Battalion The Royal Regiment of Scotland.
It is also the declared headquarters of the MI5 for their investigations into Northern Ireland-related terrorism.
