The 153rd Infantry Brigade, part of the 51st (Highland) Infantry Division, was an infantry brigade of the British Army that fought during both the First and Second world wars. It was raised in 1908, as the 2nd Highland Brigade, upon the creation of the Territorial Force and was later redesignated the 153rd (2nd 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.
