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.
M27 Infantry Automatic Rifle
The M27 IAR was adopted as the standard issue service rifle of the Marine Corps infantry - replacing the M4A1 - in 2018. Once the change is fully implemented, the M27 IAR will be issued to all riflemen in the Marine Corps infantry, while the M4A1 will only be issued to non-infantry Marines.
