The Army uses Military Occupational Specialty (MOS) codes to identify specific job specialties. Each MOS is designated by a number and letter. The first two digits represent the Career Management Field (CMF), and the letter designates the specific job within that field.

For example, 11B is an Infantryman, where “11” represents the Infantry branch and “B” identifies the specific job role.

Below are some of the main MOS categories in the Army. This is not a complete list. For the most up-to-date and comprehensive information, please visit the official U.S. Army website.
