Army MOS Codes

The Army calls their enlisted jobs military occupational specialties (MOS). When a soldier graduates from boot camp, they get their first job, their primary MOS. They then head to advanced training. During their career, they may get an additional MOS, indicating special skills or duties performed on tours or in training programs.

There are about 190 MOSs available for enlisted soldiers to choose from. Comparable specialties are grouped into branches or fields. The Army MOS is three digits. The first two digits indicate the field, and the last digit is the specific job in that field. For example, the basic career field of a soldier in the Army special forces is 18 – Special Forces. A medic in the special forces has a MOS of 18D (eighteen delta), special forces medic.
