An In-Depth Look at the MOS Codes

In the Marine Corps, Military Occupational Specialty (MOS) codes are crucial identifiers that define a Marine’s specific job or role within the organization. Each MOS code is a four-digit number that signifies a particular field and job function.

Understanding these codes is essential for anyone interested in joining the Marine Corps or those already serving who wish to explore different career paths.

The structure of MOS codes is systematic and organized to ensure clarity and precision. The first two digits of the MOS code indicate the occupational field, while the last two digits specify the particular job within that field. For example, the code 0311 refers to a Rifleman, where “03” denotes the Infantry field and “11” specifies the exact job.

There are three primary categories of MOS codes: Primary MOS (PMOS), Additional MOS (AMOS), and Combat Arms MOS. Each category serves a different purpose and helps in organizing the various roles and responsibilities within the Marine Corps.
