Which sword is the oldest weapon still in use today by the US Armed Forces?

The Mameluke Sword holds the distinction of being the oldest weapon still in use today by the US Armed Forces, specifically within the Marine Corps. Its origins trace back to the 19th century, being adopted by the Marines in 1825. The sword is modeled after the weapons carried by the Mameluke cavalry during the 18th century, which reflects a rich history and tradition.

The significance of the Mameluke Sword is not merely in its antiquity but also in what it represents for the Marine Corps—the connection to heritage, honor, and the unique traditions of the service. It is awarded to all Marine Corps officers, symbolizing their commitment to their duties and the values of the Corps.

Other swords mentioned lack the same historical depth or recognition as the Mameluke Sword within the context of the US Armed Forces. The NCO Sword, for example, is primarily associated with non-commissioned officers and not officers, while the Officer Saber is more contemporary and serves different roles in various versions of military service. The Army Sword, while significant, does not share the same lineage or recognition as the Mameluke Sword within the Marine Corps.
