Who has ultimate accountability for ensuring 3M effectiveness within the command?

• A. CO
• B. XO
• C. 3M System Coordinator
• D. Department Head

Answer: (A)

The main concept is that ultimate accountability for the command’s 3M effectiveness rests with the Commanding Officer. The CO holds the final responsibility for the command’s readiness and for ensuring the 3M program is properly implemented, resourced, trained, and reviewed. The 3M System Coordinator handles the day-to-day operation, keeps records, and makes sure the system is followed and schedules are kept, but the overall accountability stays with the CO. The Executive Officer supports execution and the Department Head takes responsibility for their own division, but they don’t carry the command-wide accountability. So the Commanding Officer is the best answer because the CO has the overarching duty to ensure the entire 3M program works effectively across the command.
