What notable feature distinguishes Marine Corps non-commissioned officers from other branches in terms of sword carrying?

Marine Corps non-commissioned officers are distinguished by being the only NCOs across the U.S. military branches who are authorized to carry swords. This includes the traditional Mameluke sword, which is a symbol of the officer rank within the Marine Corps and holds historical significance. The practice of carrying a sword by NCOs emphasizes their leadership role, authority, and ceremonial duties.

Other branches may have specific guidelines regarding sword or saber usage, but none allow non-commissioned officers the privilege of carrying swords as a standard practice. Therefore, this systemic difference showcases the unique role that Marine Corps non-commissioned officers play within their structure compared to other armed forces.
