A Chief master sergeant is the military rank for a senior non-commissioned officer in the armed forces of some countries.


Chief master sergeant is also the highest attainable rank for enlisted personnel of the Philippine Army, the Philippine Air Force and the Philippine Marine Corps (under the Philippine Navy); since 2004 as part of the ongoing modernization of the Armed Forces of the Philippines.

Above the rank is that of first chief master sergeant, created also in the same year and is bestowed on the most veteran NCO who has served in the aforementioned service branches.

The rank stands above that of senior master sergeant. The equivalent naval rating is that of master chief petty officer.

As of February 8, 2019, a new ranking classification for the Philippine National Police was adopted, eliminating confusion of old ranks. [1][2] The enabling law for the ranking is Republic Act 11200 which was signed by President Rodrigo Duterte, amending the section of the Department of the Interior and Local Government Act of 1990 that refers to the ranking classification of the Philippine National Police.[3]

The rank stands above that of Police Senior master sergeant and below Police Executive master sergeant.

Chief Master Sergeant (CMSgt) is the ninth, and highest, enlisted rank in the U.S. Air Force and the U.S. Space Force, just above Senior Master Sergeant, and is a senior non-commissioned officer rank. The official term is "Chief Master Sergeant" or "Chief".

Attaining the rank of Chief Master Sergeant is the pinnacle of an Air Force enlisted person's career. Some Chief Master Sergeants manage the efforts of all enlisted personnel within their unit or major subsection while others run major staff functions at higher headquarters levels. All Chief Master Sergeants are expected to serve as mentors for non-commissioned officers and junior enlisted members, and to serve as advisers to unit commanders and senior officers.

By federal law, no more than 1.25% of the Air Force enlisted force may hold the rank of chief master sergeant.[4]

Special duty positions[edit]

First sergeant[edit]

The E-9 pay grade of first sergeant, is special duty rank held by a senior enlisted member of a military unit who reports directly to the unit commander or deputy commander of operations. This positional billet held by a chief master sergeant and is denoted on the rank insignia by a lozenge (known colloquially as a "diamond").[5] Often referred to as the "first shirt", or "shirt", the first sergeant is responsible for the morale, welfare, and conduct of all the enlisted members in a squadron and is the chief adviser to the squadron commander concerning the enlisted force.[5] While both services don't have an actual, permanent first sergeant ranks, those who hold these positional billets are senior to their non-diamond counterparts.[5]

Group superintendent[edit]

Group superintendents fall under special reporting identifier coding with a 9G100 Air Force specialty code. Group superintendents provide leadership, management, and guidance in organizing, equipping, training, and mobilizing groups to meet home station and expeditionary mission requirements. Group superintendents work closely with their group commanders and command chief master sergeants to prepare the enlisted force to best execute mission requirements. They manage and direct resource activities as well as interpret and enforce policies and applicable directives. They also establish control procedures to meet mission goals and standards. Additionally, they recommend or initiate actions to improve organizational effectiveness and efficiency as well as ensure that the management of personnel and resources are consistent with current practices and procedures in support of the wing's mission. They resolve issues between subordinate squadrons, other groups, wing staff, and outside agencies as well as perform other duties as directed by their group commanders.[6]

Squadron Superintendent[edit]

The duty position of squadron superintendent is the senior enlisted advisor to a unit commander and provides the parent organization(s) with subject matter expertise on the units capabilities.

Wing Weapons Manager[edit]

The Wing Weapons Manager (WWM) is the wing's focal point for all weapons loading and armament systems related matters and serves as the functional manager for all assigned 2W1X1’s. The WWM's primary efforts focus on compliance, continuity, and standardization. The WWM will be a 2W100 CMSgt assigned directly to the MXG/CC. Weapons activities required to support the generation of peacetime training sorties generally do not reinforce primary combat skills. Therefore, the WWM plays a key role in ensuring that the unit is able to produce combat loaded aircraft. The WWM is charged with providing technical and managerial advice to senior leaders in matters of weapons loading and armament systems. The WWM coordinates with the Aircraft Maintenance Squadrons, Weapons Sections, Armament Flight, Wing Safety, Wing Weapons and Tactics Officer, the Munitions Squadron/Flight, and other unit agencies on weapons related matters. The WWM is a certifying official and evaluator for weapons loading task certifications and qualifications.

Senior enlisted advisors[edit]

Command Chief Master Sergeant[edit]

The position of command chief master sergeant (CCM) is unique as it is considered a rank and billet. Formerly, the billets were called senior enlisted advisors and were held by a chief master sergeant. These billets were turned into a permanent rank of command chief master sergeants in November 1998. Command chief master sergeants serve as the senior enlisted advisors to commanders at key levels of command; these include Wings, Numbered Air Forces, Field Operating Agencies, and Major Commands. In a Joint Command, when an Air Force Chief fills a DoD-nominated Command senior enlisted advisor position (see note), that individual is also designated as a Command Chief. Command Chiefs advise the unit commanders on all enlisted matters, including all issues affecting the command's mission and operations, and the readiness, training, utilization, morale, technical and professional development, and quality of life of all enlisted members in the organization. Command Chiefs hold a reporting identifier of 9E000. CCMs provide leadership to the enlisted force and are the functional managers for group superintendents and first sergeants in their organizations.[7][8]

Historical notes[edit]

Although the Air Force had been an independent service since 1947, the rank of chief master Sergeant did not come into being until the authorization of the Military Pay Act of 1958. This act established the pay grades of E-8 and E-9, but without specifying titles for those pay grades. It wasn't until late 1958 that the title chief master sergeant (and the accompanying rank insignia) was decided upon.

The original Chief Master Sergeant rank insignia (1958–1994) consisted of 2 chevrons on top, 3 stripes in the middle, and 3 rockers on bottom.

Until his retirement in 2003, Chief Master Sergeant Norman Marous was the Air Force's senior-most chief master sergeant, having served in the Air Force since 1962. Marous left active duty in 1967 to spend 22 years in the USAF Reserve and National Guard before returning to active duty as a Chief Master Sergeant in 1989. He retired in 2003 with 41½ years of service. He is the only person authorized to wear two longevity ribbons, due to the space required for the number of multiple award devices authorized.[9]
