Who holds ultimate responsibility for the effective functioning of the 3-M system within the command?

The Commanding Officer holds ultimate responsibility for the effective functioning of the 3-M (Maintenance and Material Management) system within the command. This is due to the Commanding Officer's role as the leader who is accountable for all operations, resources, and personnel within the command. The 3-M system is critical for ensuring proper maintenance and material readiness, which directly impacts the command's operational capability.

While the other positions such as the Executive Officer, 3-M Coordinator, or Engineering Officer have significant roles in managing and overseeing different aspects of the 3-M system, they operate under the authority and guidance of the Commanding Officer. The Commanding Officer creates the overall policy and framework within which these managers operate, ensuring that the system is effectively implemented and maintained throughout the command. Therefore, the ultimate accountability for the success of the 3-M program resides with the Commanding Officer.
