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.
Model 1840 army noncommissioned officers' sword
The M1840 has had a long service life, seeing frontline service from the Mexican War until the Spanish–American War. In 1868 the ordnance board recommended that no more leather sword, or bayonet scabbards be purchased, so after the leather ones were used up, a black Japanned steel scabbard was substituted, along with a new pattern leather frog. It remained in service as a ceremonial weapon until general orders No. 77 dated August 6, 1875 discontinued its use. A modern version of this sword with steel scabbard is currently permitted for wear by US Army platoon sergeants and first sergeants; in practice it is rarely seen outside the 3rd Infantry Regiment (the "Old Guard") and honor guards. Some army NCOs have this sword and wear it for social occasions, regardless of duty as a platoon sergeant or first sergeant.
