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.
Air Force Training Ribbon
The United States Marine Corps also lacks an equivalent ribbon, but instead awards their trademark Eagle, Globe & Anchor insignia upon completion of Recruit Training or Officer Candidate School, or at commissioning for those Marine Corps officers accessed via the United States Naval Academy (USNA), Naval ROTC (NROTC) Marine Corps Option or USMC Platoon Leaders Class (PLC). Like the Navy and the Coast Guard, wear of the Air Force Training Ribbon is also prohibited on all USMC uniforms worn by former USAF personnel.
