Navy and Coast Guard Uniform

The use of the word "rank" for Navy enlisted personnel is incorrect. The term is "rate." The rating badge — a combination of rate (pay grade) and rating (specialty) is worn on the left upper sleeve of all uniforms in grades E-4 through E-6. E-1 through E-3 have color coded group rate marks based upon their occupational field. Group rate marks for E-1 (optional) through E-3 are worn on dress uniforms only. Chief Petty Officers (E-7 through E-9) wear collar devices on their white and khaki uniforms, and rate badges on their Service Dress Blues.

This officers' crest is worn on the Navy officer's cap. A large one is worn on the combination cap — the cap with the black bill and cloth cover, and a smaller one is worn on the left side of the garrison cap.

Navy Commissioned and Warrant Officers

Navy officers wear their rank devices in different places on their uniforms, depending upon the uniform. The three basic uniforms and the type of rank devices are: khakis (a working uniform) — pins on the collar; whites — stripes on shoulder boards; and, blues — stripes sewn on the lower sleeve. Shoulder boards are also worn on bridge coats and reefers. The collar devices are also worn on the right side of the garrison cap (a miniature officer's crest is worn on the left) and slightly larger devices are worn on the epaulets of the raincoat and working jacket.

Additionally, line officers wear a star above the stripes of the shoulder boards or sleeves but staff and warrant officers wear specialty insignia.

Specialty Insignia - LDO and Warrant

Commissioned officers in the Navy are either Line officers or Staff Corps officers. Some have advanced through the enlisted rates and are designated for duty in certain technical fields. These are Limited Duty Officers (LDO) and commisisoned warrant officers (CWO). CWOs and Staff corps LDOs wear their specialty insignia on the sleeve of the dress blue uniforms and on their shoulder boards in place of the star worn by Line officers. On Winter Blue and khaki uniforms, the specialty insignia is a collar device worn on the left collar while the rank device is worn on the right.

Enlisted Rating Insignia

The enlisted rating badge for Petty Officer Third Class and above consists of two parts. The chevrons indicate pay grade (rate). Between the chevrons and the eagle is an insignia indicating the Sailor's job speciality (rating). Insignia are white on blue uniforms and Navy blue on white uniforms. Sailors in pay grades E-4 through E-6 can be addressed as "Petty Officer (name)" or [as example] "Boatswain's Mate Third Class (name)". The latter would be written as BM3.

Chief Petty Officers are always referred to as "Chief", "Senior Chief", or "Master Chief" as appropriate. As example: "Chief Jones" or in subsequent references, just "Chief".

The tables show the rating insignia for various Navy specialities. For clarity, the insignia are displayed in these groupings:

Group Rate Marks
for
Pay Grades E-1 through E-3

Sailors in pay grades E-1 through E-3 are considered to be in apprenticeships. As they begin their path towards advancement to Petty Officer in a specific specialty, they begin in the appropriate "group". For example, a Sailor who wishes to be an Electrician's Mate will begin in the Engineering/Hull group. The groups and the general rate marks (stripes) for E-1 through E-3 are shown here. (Note: E-1s do not wear any rate marks.) These rate marks are shown for the dress blue uniform. For whites, the background is white and the stripes are Navy blue. Those who earn it through a training school [an "A" school] or by passing a Navywide examination will wear a rating insignia above the stripes.
