A U.S. Navy Chief Petty Officer is the seventh highest rank among enlisted personnel in the Navy. The rank is above petty officer first class, but below senior chief petty officer.
A Chief Petty Officer possesses expanded powers and responsibilities over ranks that fall that below it. Responsibilities include training junior officers and overseeing the sailors and petty officers in his division. The rank affords him significant benefits above those received by Petty Officers or enlisted sailors, such as private living quarters and use of the chief's mess. Chief Petty Officers are usually promoted from Petty Officer First Class, but can be promoted from lower paygrades depending on demonstrated leadership and experience.
