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. Formerly the rank was Master and Commander, and Commanders traditionally are known as Captain by courtesy.
A Commander in the U.S. Navy commands a Frigate, Destroyer, Submarine or shore installation, or is second in command to a Captain.
Sometimes the term kommandant is used.
