Who has the ultimate authority over mission readiness and welfare of the unit?

• A. The Executive Officer (XO)
• B. The Commanding Officer (CO)
• C. Command Master Chief (CMC)
• D. Department Head

Answer: (B)

Ultimate authority over mission readiness and welfare rests with the Commanding Officer. The CO is responsible for the unit’s mission success, training and qualifications, equipment and maintenance readiness, safety programs, and the welfare and morale of all personnel. They set priorities, approve resources, and make final decisions that affect how ready the unit is to execute its mission. The Executive Officer supports the CO, handling day-to-day operations and acting as the commander in the CO’s absence, but ultimate accountability stays with the CO. The Command Master Chief advises on enlisted welfare and morale, providing critical insight to the CO, yet does not hold final authority over readiness. Department Heads manage their own divisions and ensure their components meet readiness standards, but their authority answers up to the CO to maintain overall unit readiness.
