Duties and Responsibilities: Security of the starship/station and its personnel is paramount. For this reason, the security officer is responsible for internal security. This can range from security for visiting diplomats to counter-insurgency. Additionally, the CSecO is responsible for securing all handheld weapons on the ship.
External Security - During away team missions, personnel are vulnerable to attack. For this reason, the security officer is responsible for arranging security for officers away from the starship/station. He is responsible for securing and maintaining safety for the ship and its crew, from both internal and external threats, and is usually an integral member of most away teams.
The CSecO generally has a large staff relative to the size of the vessel, and will have an office for coordinating their functions and schedules on larger ships. Security officers may also function as damage control officers and tactical officers when required.
In most cases, this position is synonymous with the Chief Tactical Officer. In cases where a ship's circumstances or mission profile warrant a dedicated CTO, the CSecO will focus on shipboard security and ground combat where necessary.
