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.
Uniforms of the United States Marine Corps
Various uniforms display rank insignia differently. Enlisted Marines will wear chevrons on the sleeves of all uniforms but the Utility and other working uniforms: gold stripes on red for the Dress coat, green stripes on red for the service coat, green stripes on khaki for the khaki short and long sleeve shirts, and black metal or plastic pin-on insignia on the collar of the utility and other working uniforms and the all-weather coat. The same insignia is pinned on the epaulettes of the wool sweaters and tanker jacket. Officers will wear large insignia on the epaulettes of dress, evening dress, and service coats as well as sweaters and tanker jacket; smaller insignia is worn on the collar of all other uniforms (officers in a combat environment may wear subdued insignia, where flat black replaces silver and flat brown replaces gold). Chief Warrant Officers who are designated "Infantry Weapons Officer" with an MOS of 0306 (also known as "Marine Gunner") replace their left insignia with a gold or black bursting bomb. Navy personnel authorized to wear Marine uniforms wear their assigned rate. Musicians in the United States Marine Band replace the crossed rifle in their insignia with lyres to denote their non-combat role.
