Security investigations officer

The Security Investigations Officer is the security specialist who assists the Chief of Security in any ongoing investigations. The role varies and will often involve crime-scene investigation as well as 'detective-like' activities. If there are no ongoing investigations, the SIO will take his or her place on a regular security team.

In the early part of his career, Commodore Jason Fisher specialized as a security investigations officer. In 2383, the SIO aboard Starbase 74 was Darius D'Celta.
