OR-4

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

The term is sometimes considered to exclude warrant officers, and occasionally also excludes NCOs.

In the United States military, and in the military forces of many non-Commonwealth countries, the equivalent term is enlisted rank, which generally includes non-commissioned officers (unless specifying junior enlisted), but always excludes the American type of warrant officer.

In the "standard rank scale" maintained by NATO, "other ranks" are coded from OR1 (lowest) to OR9.

In British India, a distinction was made between British other ranks (BORs) and Indian other ranks (IORs).
