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 specialty (rating). Insignia are silver 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 linked tables show the rating insignia for various Navy specialties. For clarity, the insignia are displayed in these groupings:
