Who are the primary watchstanders and teams involved in CSOSS execution on a surface combatant?

• A. The Captain and Executive Officer.
• B. The Tactical Action Officer (TAO) and CIC watch team (CIC Watch Officer, Sensor and Weapons controllers) along with platform-specific system operators.
• C. Engineering Supervisors.
• D. The Legal Officer and Navigator.

Answer: (B)

The action on a surface combatant hinges on a dedicated battle staff that actually runs the CSOSS procedures. The primary watchstanders are the Tactical Action Officer and the CIC watch team, which includes the CIC Watch Officer and the Sensor and Weapons Controllers, plus the platform-specific system operators who run the ship’s combat systems. The TAO is the senior tactical authority in CIC and coordinates the overall execution of CSOSS, while the CIC Watch Officer leads the daily tactical operations and directs the Sensor Controllers (who process radar and sensor data) and the Weapons Controllers (who manage fire-control solutions and weapon status). The platform-specific system operators support by maintaining and operating the individual combat-system equipment, such as radars, IFF, and missile or gun systems. Together, they observe, decide, and act to maintain the battlespace picture and execute engagements under the TAO’s direction. Roles like the Captain or Executive Officer provide overall command guidance but do not perform the day-to-day CSOSS execution; Engineering Supervisors and other staff have different primary responsibilities not focused on CSOSS battle execution.
