The United States Navy classifies its enlisted personel with a system of rating (job speciality) and rate (military rank). For example, an Aerographer's Mate First Class would be AG1; the AG indicates the rating (Aerographer's Mate) while the 1 indicates the rate (First Class Petty Officer).

Naval Enlisted Sailors are referred to casually by their rating. For example, Yeoman First Class John Smith would casually be referred to as YN1 (said: "Y, N, one"). U.S. Navy officers do not have ratings.

Also included in a sailor's rating is their "community"; for example, if Yeoman First Class Smith has earned his enlisted submarine qualification, his title would be YN1(SS) John Smith. It is possible to "stack" these if an individual has earned multiple qualifications.
