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.
M16 rifle
The Marine Corps had long maintained the full-length M16 as their standard infantry rifle, but in October 2015 the switch to the M4 carbine was approved as the standard-issue weapon, giving Marine infantrymen a smaller and more compact weapon. Enough M4s are already in the inventory to re-equip all necessary units by September 2016, and M16A4s will be moved to support and non-infantry Marines.
