During the Great War, many regiments of the Commonwealth forces wore the kilt not only as a dress or garrison uniform element, but also in the field. Among these units, the most well known were the Royal Highlanders (Black Watch tartan), Cameron Highlanders (Cameron tartan), Gordon Highlanders (Gordon tartan), the Seaforth Highlanders (MacKenzie tartan), and the Argyll and Sutherland Highlanders.
Of the Territorial Forces, a few individual battalions of certain regiments wore kilts such as the 6th Battalion and 9th Battalions of the Highland Light Infantry and the 9th Battalion (The Dandy Ninth) of the Royal Scots. In addition other Regiments contained kilted battalions.
