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 1850 Army Staff &amp; Field Officers' Sword
The Model 1850 Army Staff and Field Officer's Sword was carried by all members of staff departments,
Field Grade officers of Artillery and Infantry, Company Grade Officers of Light Artillery, Staff Officers and
Aides-de-Camp between 1850 and 1872. It was based on a French pattern. Though other swords were by regulation allowed, this model was by far the most popular sword carried by officers during the American Civil War. The Staff and Field Officers' Sword is distinct from the Model 1850 Army Foot Officer's Sword.
