Īlong with the Rifles, the Royal Regiment of Scotland is also one of only two line infantry regiments to maintain its own regular military band within the Royal Corps of Army Music, which was formed through the amalgamation of the Highland band and Lowland band of the Scottish Division. There is however a common regimental cap badge, tactical recognition flash (TRF), tartan, stable belt and Glengarry headdress but distinctively coloured hackles are also worn by each separate battalion on the Tam o' Shanter headdress to maintain their individual identity and the pipes and drums of each battalion continue to wear the ceremonial uniforms and tartans of their former regiments. Of all of the new regiments formed following the announcement of 16 December 2004, the Royal Regiment of Scotland is the only one where the former regimental titles have been prominently retained with the new numbered battalion designations as subtitles.

The regiment consisted originally of a total of seven battalions: one of these was formed by the amalgamation of the Royal Scots and King's Own Scottish Borderers, while the others are each formed from one of the remaining single-battalion regiments of the Scottish Division. As part of restructuring in the British Army, the Royal Regiment of Scotland's creation was announced by the Secretary of State for Defence, Geoff Hoon in the House of Commons on 16 December 2004, after the merger of several regiments and the reduction in total regular infantry battalions from 40 to 36 was outlined in the defence white paper, Delivering Security in a Changing World, several months earlier.
