Commander

Commander is a military rank used in many navies but not generally in armies or air forces. It is below Captain and above Lieutenant-Commander. The rank evolved in the 18th and early 19th centuries and was originally known as Master and Commander. The Royal Navy shortened Master and Commander to Commander in 1814.

American police rank

The San Francisco police department is one of the few American police departments which use this rank. A Commander in the SFPD is equivalent to an Inspector in other US departments (such as the NYPD); the SFPD rank was originally called Inspector as well, but was changed to Commander after senior officers voiced a preference for the more military-sounding rank.
