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 Navy
As the Marines do not have medical personnel and chaplains, the Navy provides them. The officers and enlisted include doctors, physician assistants, dentists, nurses, hospital corpsmen, chaplains, religious program specialists, and Naval Gunfire Liaison Officers. There are also specialized ratings that will be attached to Marine commands such as Navy Divers for example. Because of this relationship, these personnel are authorized to wear U.S. Marine Corps utility (desert/woodland) uniforms with Navy rank insignia replacing the Marine insignia for enlisted personnel (Navy and Marine officer rank insignia are identical) and with a "U.S. Navy" patch replacing the "U.S. Marines" one. They wear the 8-point utility cover, but it lacks the Marine Corps emblem. Additionally, Navy personnel attached to Marine units can elect to wear Marine service uniforms, with Navy insignia. Those opting to wear Marine Corps service uniforms must meet Marine Corps grooming and physical appearance standards, which are more stringent than Navy standards. This does not apply to the MARPAT uniforms, as this uniform is required for wear in the field when attached to Marine units, regardless of adherence to Marine Corps grooming standards. Navy personnel are not authorized to wear the Marine Corps Dress Blue Uniform; instead Navy Dress Blue and White uniforms are worn.
