In the context of the military, particularly the U.S. Army, “MOS” stands for “Military Occupational Specialty.” This term refers to a specific job or career field that a soldier is trained for and assigned to within the Army. Each MOS is designated by a unique code, which typically consists of a number and a letter (for example, 11B for an Infantryman or 68W for a Combat Medic).
The MOS system is designed to categorize various roles and responsibilities within the military, ensuring that soldiers are trained for the specific tasks they will be performing. Soldiers receive training related to their MOS during Basic Combat Training (BCT) and further specialized training at Advanced Individual Training (AIT).
An MOS can encompass a wide range of fields, including combat roles, technical and support roles, medical positions, administrative roles, and more. Each MOS has its own training requirements, responsibilities, and career progression opportunities within the Army.
