Security chief

The security chief (or chief of security) is the officer in charge of the security division of a starship or starbase.

In the Earth Starfleet, the armory officer was in charge of a ship's security department.

In the mid-23rd century Federation Starfleet a security chief, like Lieutenant Commander Giotto of the USS Enterprise (NCC-1701), was not necessarily a bridge officer. 

In the 2270s, the role of security chief was combined with that of the chief tactical officer. The chief tactical officer could be a separate position or be combined with that of helmsman or navigator. 

In the 24th century, with helm and navigation consolidated in the new flight controller position, the chief tactical officer fulfilled the role of security chief. Aboard the USS Voyager, Lieutenant Commander Tuvok, as security chief, had thirteen department heads report to him every day on ship's protocol. 

On some starbases, such as Deep Space 9, the chief of security was a separate position from the tactical officer and was also referred to as head of security.
