A sword may be worn when the individual is in command of troops in formation—the Mameluke sword for officers, the NCO sword for NCOs and SNCOs. When wearing the sword and Dress Blue coat, officers wear the Sam Browne belt. For enlisted, the sword is worn with a white waistbelt and brass buckle when wearing the Dress Blue coat. The Marine Corps is the only branch of the United States military which regularly allows NCOs to carry a sword. For enlisted Marines, they earn the right to carry the NCO sword and wear the scarlet blood stripe on their blue trousers when they achieve the rank of Corporal.
