List of United States Army careers

The United States Army uses various personnel management systems to classify soldiers in different specialties which they receive specialized and formal training on once they have successfully completed Basic Combat Training (BCT).

Enlisted soldiers are categorized by their assigned job called a Military Occupational Specialty (MOS).

MOS are labeled with a short alphanumerical code called a military occupational core specialty code (MOSC), which consists of a two-digit number appended by a Latin letter.

Related AOCs are grouped together by specific branch of the Army or by broader in scope functional areas (FA).

Changes include deleting obsolete jobs, merging redundant jobs, and using common numbers for both enlisted CMFs and officer AOCs (e.g. "35" is military intelligence for both officers and enlisted).
