Enlisted rank

An enlisted rank (also known as an enlisted grade or enlisted rate) is, in most militaries, any rank below that of a commissioned officer. The term can also be inclusive of non-commissioned officers or warrant officers. In most cases, enlisted service personnel perform jobs specific to their own occupational specialty, as opposed to the more generalized command responsibilities of commissioned officers.

British Armed Forces
In the British Armed Forces and the armed force of other Commonwealth countries (except Canada), the equivalent term in respect of armies and air forces is Other Rank (or OR for short), while navies use the term rating.

Canadian Forces
In the Canadian Forces, the term non-commissioned member (NCM) is used.

North Atlantic Treaty Organization
In the "standard rank scale" maintained by the North Atlantic Treaty Organization, non-commissioned ranks are coded OR1–OR9 (bottom to top), OR being an abbreviation for Other Ranks.

United States Armed Forces
The five branches all use the same "E-" designation for enlisted pay grades, with service-specific names applied to each (e.g., Chief Petty Officer, Master Gunnery Sergeant, Private First Class). Each branch incorporates it as part of a service member's job specialty designator. In the United States Air Force, this job specialty designator is known as an Air Force Specialty Code, in the United States Army and United States Marine Corps, a Military Occupational Specialty, and in the United States Navy and United States Coast Guard, a naval rating.
