Who provides air, water, and power to the combat system?

• A. TAO
• B. EOOW
• C. CSRO
• D. CO

Answer: (B)

The question tests understanding of who is responsible for supplying essential utilities to the combat system. The Engineering Officer of the Watch is in charge of the ship’s engineering plant and its daily operation, including providing the necessary air, water, and electrical power to all shipboard equipment. That means keeping the ventilation and pneumatic systems supplied with air, supplying cooling and other water needs for the equipment, and ensuring reliable electrical power distribution to the combat system so sensors, weapons, and related gear function properly.

The other roles have different focuses: the Tactical Action Officer handles the tactical employment and decision-making of the combat system, not its utilities; the Combat Systems Readiness Officer ensures the systems are ready and maintained but doesn’t manage the actual provisioning of air, water, and power; and the Commanding Officer is the overall authority who delegates duties to the crew.
