United States Marine Corps noncommissioned officer's sword
The Marine Corps noncommissioned officer's sword is a sword worn by noncommissioned officers (NCOs) and staff noncommissioned officers (SNCOs) of the United States Marine Corps. The NCO sword was adopted in 1859 and is patterned after the United States Army's foot officers' sword of 1850. The M1859 NCO sword continues service today as the Marine Corps drill and ceremonial sword. The sword's use is restricted by regulation to ceremonial occasions by an NCO or Staff NCO in command of troops under arms or at weddings and wedding receptions where at least one of those being married is in uniform and has the rank of Corporal or higher.
Mameluke sword
Perhaps due to the Marines' distinguished record during this campaign, including the capture of the Tripolitan city of Derna after a long and dangerous desert march, Marine Corps Commandant Archibald Henderson adopted the Mameluke sword in 1825 for wear by Marine officers. After initial distribution in 1826, Mameluke swords have been worn except for the years 1859–1875 (when Marine officers were required to wear the U.S. Model 1850 Army foot officers' sword), and a brief period when swords were suspended during World War II. Since that time, Mameluke swords have been worn by Marine officers in a continuing tradition to the present day.
