Other ranks (ORs) in the Royal Marines, British Army, Royal Air Force, and in the armies and air forces of many other Commonwealth countries and the Republic of Ireland, are those personnel who are not commissioned officers, usually including non-commissioned officers (NCOs). In the Royal Navy, these personnel are called "ratings" rather than "other ranks". Non-commissioned member is the equivalent term for the Canadian Armed Forces. Colloquially, members of the other ranks are known as "rankers".
