First referenced in OPNAVINST 1306.2C dated 16 October 1995, the Navy's Command Master Chief (CMC) Program is a valuable asset which stimulates free-flowing communications and ensures the highest standards of professionalism are upheld at all levels within the chain of command. Command Master Chiefs strengthen the chain of command by keeping the Commanding Officer aware of existing or potential situations as well as procedures and practices which affect the mission, readiness, welfare and morale of the Sailors in the command.
