Other ranks (ORs) in the Royal Marines (RM), the British Army, and the Royal Air Force (RAF), along with the navies, armies, and air forces of many other Commonwealth countries and Ireland, are those personnel who are not commissioned officers, but usually include non-commissioned officers (NCOs). In the Royal Navy (RN), these personnel are called "ratings" rather than "other ranks". "Non-commissioned member" (NCM) is the equivalent term in the Canadian Armed Forces, and "enlisted rank" is used in the United States and elsewhere.
