The patches shown were adopted by the division during late 1917, and were designed to a brigade scheme including a brigade sign worn by all ranks on the back, below the collar. Those signs for the 92nd and 93rd brigades indicated the battalion seniority, all brigades wore their battalion, M.G. company and T.M. battery signs at the top of both sleeves.
