The 154th Infantry Brigade (part of the 51st (Highland) Infantry Division) was an infantry brigade of the British Army division that fought during both the First and Second world wars. The brigade was raised in 1908, upon the creation of the Territorial Force, as the Argyll and Sutherland Brigade and was later redesignated as the 154th (3rd Highland) Brigade. The division was referred to as the "Highway Decorators" by other divisions who became used to discovering the 'HD' insignia painted wherever the Highlanders had passed through.
