From Wikipedia, the free encyclopedia
Staff Corporal (SCpl or S/Cpl) is the equivalent rank to Staff Sergeant in the Household Cavalry, ranking between Corporal of Horse and Warrant Officer Class 2. He may hold an appointment such as Squadron Quartermaster Corporal. A Staff Corporal wears four point-up rank chevrons on his cuff, surmounted by a crown. Staff Corporals are actually addressed as "Corporal-Major" by superiors and usually as "Sir" by juniors, a holdover from the fact that the equivalent rank was originally Troop Corporal-Major.
