Commanding officer

A commanding officer (or CO) is a term used to describe one's rank in relation to others within the same environment.

One meaning of commanding officer is the highest-ranking officer and commander of a unit. On starships, the CO usually has the rank of Captain, though sometimes a Commander, Commodore or Fleet Captain may also hold this position. On starbases, the CO is sometimes referred to as "portmaster" and was usually a captain or a flag officer.

On starships, it is general practice to address the commanding officer as "Captain," regardless of their actual rank or position.
