MILITARY OCCUPATIONAL SPECIALTY (MOS) CODES,
AF SPECIALITY CODES (AFSC), & NAVY ENLISTED CLASSIFICATION CODES


Army and MC Military Occupational Specialty (MOS) Codes, AF Specialty Codes (AFSC), and Navy Enlisted Classification Codes (NEC) identify a member’s job title, position description and job qualifications.  Normally, member’s are assigned a primary MOS (e.g. infantryman) and a secondary MOS for their day-to-day job classification.  If the requester requires a complete description of the duties of a particular MOS, AFSC, or NEC, that information will be found in manuals which are currently located in the Reference Libraries of the respective branches.  Machine copies can be reproduced for the requester.
