What sword is used by Marine Corps non-commissioned officers?

The correct answer is the Mameluke Sword. This sword holds a significant place in Marine Corps tradition and history, as it is the ceremonial sword carried by Marine Corps officers and is especially notable for its use by non-commissioned officers. The Mameluke Sword traces its origins back to the early 19th century and symbolizes leadership, honor, and commitment.

While there are other swords mentioned, such as the Army Infantry Sword, NCO Sword, and Naval Cutlass, they are associated with different branches or functions. The Army Infantry Sword is specific to the Army, the NCO Sword is generally used in various branches as a standard designation for non-commissioned officer swords but is not unique to the Marine Corps, and the Naval Cutlass serves a different ceremonial and practical purpose within the Navy. The Mameluke Sword remains a distinct emblem of rank and tradition for Marine Corps non-commissioned officers, reflecting their unique history and the values of the Corps.
