The enlisted rating badge for Petty Officer Third Class and above consists of two parts. The chevrons indicated the pay grade (rate). Between the chevrons and the eagle is a speciality insignia indicating the Sailor's job speciality (rating). These insignia appear in white on blue uniforms and Navy blue on white uniforms. Because of the number, this group has been split into two tables. This table shows the rating insignia for administration, deck, medical, and weapons specialties for those ratings beginning with the letters B through L. The second table is letters M through Y. The other groups are Aviation, Construction, and Engineering.
