On 28 March 2006, as part of the restructuring of the infantry, the Argyll and Sutherland Highlanders were amalgamated with the other Scottish infantry regiments into the single Royal Regiment of Scotland. The regiment's last role before amalgamation was in the air assault role as part of 16 Air Assault Brigade. Elements of the new regiment originally affiliated with the Argyll and Sutherland Highlanders included a regular battalion (5 SCOTS), an affiliated company of the Territorial Army battalion, 51st Highland Volunteers (7 SCOTS) and an Army Cadet Force battalion. The 5th Battalion continued recruiting in the area allocated to the Argylls, wore a green hackle on its headdress to differentiate it from the other battalions, and were permitted to use the title "The Argyll and Sutherland Highlanders" in reference to the battalion.
