The Battalion's primary operational role is to provide reserve contingents to augment its two affiliated regular Battalions and the wider Royal Regiment of Scotland during any Large Scale Deliberate Intervention (LSDI) Operations. Many members routinely volunteer to serve individually alongside their affiliated regular Battalions or as part of Territorial composite sub-unit formations of up to company-sized strength on exercise and operations all over the world, including Cyprus, Bosnia, Kosovo, Northern Ireland and, most recently, on Operation Herrick in Afghanistan and Operation Telic in Iraq, especially on TELIC II and TELIC IV, the former on which two fatalities were suffered in 2003, whilst attached to the King's Own Scottish Borderers. 52nd Lowland Regiment was also noted for its involvement in the defence of CIMIC-House in Al Amarah during August 2004.
