What military services authorize their NCOs to carry swords?

The Marine Corps uniquely emphasizes the tradition and symbolism of carrying swords as part of its customs and ceremonies. The Marine Corps Sword is a significant emblem of honor, leadership, and the commitment expected of non-commissioned officers (NCOs). In the Marine Corps, the sword serves both functional and ceremonial purposes, representing the authority of an NCO and their role as leaders within the unit.

While other branches of the military may have their own ceremonial swords or insignias, the sword is not a standard or authorized sidearm for NCOs in those services. Thus, the Marine Corps stands out for allowing NCOs to carry swords as a formal part of their dress uniform, reinforcing the distinct culture and traditions within the Corps.
