The Chief Petty Officer (MCPO) is an enlisted rank in some navies, with an E- salary grade in the United States Navy and the United States Coast Guard, just above the Superior Petty Officer (SCPO). Chief NCOs are referred to as Master Chief (surname) in colloquial contexts, and they constitute the 1.25% highest of the enlisted members of the maritime forces. Leadership responsibility increases significantly in mid-level enlisted ranks, which is formally recognized through the use of the terms NCO and NCO. A sergeant in the Army, a sergeant in the Air Force, and a corporal in the Navy are considered non-commissioned officers.
The equivalent of Navy Petty Officer, NCO, is achieved in the rank of third class warrant officer. Leadership responsibility increases significantly in mid-level enlisted ranks. A sergeant in the Army, a sergeant in the Air Force, and a corporal in the Navy are considered non-commissioned officer ranks. A chief warrant officer will be appointed chief warrant officer of command, called the head of the ship in a submarine.
The Chief Petty Officer of the Coast Guard (MCPOCG) is appointed by the Commander of the Coast Guard to serve as the highest-ranking enlisted member in the Coast Guard. The Chief Warrant Officer (SCPO) is the second chief warrant officer in the United States Navy. Instead of a qualified test, SCPO candidates are evaluated by a board of current chief non-commissioned officers based on their leadership skills and performance. A chief non-commissioned officer of the force (FORCM) is a chief chief who has virtually the same responsibility as the main command chiefs, but for larger force commands rather than a single unit.
If selected, a Master Chief receives additional leadership training and is assigned to a command as Master Command Chief (CMC). In the Coast Guard, promotion to Chief NCO is similar to other advancements that consist of competing with other senior NCOs eligible for advancement. Lower-ranking NCOs serve under a court order, but receive commissions from the president upon promotion to chief warrant officer 2.A senior chief warrant officer is usually promoted to chief warrant officer (CPO), although promotion of lower salary ratings can occur with a sufficient display of leadership and experience. A 1958 amendment to the Career Compensation Act added two new salary grades, senior boss (E) and principal boss (E), and created six new qualification titles. The chief warrant officer can be an interim (temporary) appointment, appointed as an AA, or a permanent appointment, appointed as a PA.
A Chief Fleet Petty Officer (FLTCM) is a chief chief who, again, has virtually the same responsibility as the main command chiefs, but for larger fleet commandos. The Chief Petty Officer adjusts the propeller mechanism of a torpedo while loading onto a submarine in New London, Connecticut, around July 1943. Most importantly, chiefs reduce the gap between officers and enlisted personnel, acting as supervisors and advocates for their sailors.
