The United States Marine Corps Military Occupational Specialty (MOS) is a system of categorizing career fields. All enlisted and officer Marines are assigned a four-digit code denoting their primary occupational field and specialty. Additional MOSs may be assigned through a combination of training and/or experience, which may or may not include completion of a formal school and assignment of a formal school code.

Occupational Fields (OccFlds) are identified in the first two digits and represents a grouping of related MOSs. Job codes are identified in the last two digits and represent a specific job within that OccFld.

The USMC now publishes an annual Navy/Marine Corps joint publication (NAVMC) directive in the 1200 Standard Subject Identification Code (SSIC) series to capture changes to the MOS system. Previous versions of MCO 1200.17_ series directives are cancelled, including MCO 1200.17E, the last in the series before beginning the annual NAVMC-type directive series.[1][2]

On 30 June 2016, the Marine Corps announced the renaming of 19 MOSs with gender-neutral job titles, replacing the word or word-part "man" with the word "Marine" in most.[3] Not all instances of the word or word-part "man" were removed, e.g., 0171 Manpower Information Systems (MIS) Analyst, 0311 Rifleman, 0341 Mortarman.

On 15 October 2020, the Marine Corps announced a structured review of 67 Marine Corps MOSs. This review is part of a larger Marine Corps force redesign initiated in March 2020 which was initiated to help the Corps re-align for the future.[4]

Restrictions on officer MOSs include:[2]

  1. Restricted officers (limited duty officers and warrant officers) cannot hold non-primary MOSs and will be limited to Primary MOS (PMOS) – Basic MOS (BMOS) matches.
  2. Colonels are considered fully qualified Marine Air Ground Task Force (MAGTF) Officers and, with the exception of lawyers and MOSs 8059/61 Acquisition Management Professionals, will only hold MOSs 8040, 8041, or 8042 as PMOS. Non-PMOSs will not be associated in current service records with General Officers and Colonels, with the exception of MOSs 822X/824X Foreign Area Officers and Regional Affairs Officers.
  3. MOSs must be required in sufficient numbers as Billet MOSs (BMOS) in the Total Force Structure Manpower System (TFSMS) to be justified. MOSs with no Table of Organization (T/O) requirement or no inventory are subject to deletion/disapproval.
  4. MOSs must serve a Human Resources Development Process (HRDP) purpose (establish a skill requirement, manpower planning, manages the forces, manage training, identify special pay billets). MOSs not meeting this criterion will be deemed nonperforming MOSs and subject to deletion/disapproval.
  5. A single track is limited to a single MOS. Separate MOSs are not appropriate based on grade changes unless merging with other MOSs.

An enlisted applicant (male or female) seeking a Program Enlisted For (PEF) code associated with MOSs 0311, 0313, 0321, 0331, 0341, 0351, 0352, 0811, 0842, 0844, 0847, 0861, 1371, 1812, 1833, 2131, 2141, 2146, 2147, or 7212 must meet certain gender-neutral physical standards. For the Initial Strength Test (IST), the applicant must achieve 3 pull-ups, a 13:30 1.5-mile run, 44 crunches, and 45 ammo can lifts. The MOS Classification Standards based on a recruits final CFT and PFT are: 6 pull-ups, 24:51 3-mile run, 3:12 Maneuver Under Fire Course, 3:26 Movement to Contact Court, and 60 ammo can lifts.

Below are listed the current authorized Marine Corps MOSs, organized by OccFld, then by specific MOS. Most MOSs have specific rank/pay grade requirements and are listed to the right of the MOS title, if applicable (see United States Marine Corps rank insignia), abbreviated from the highest allowed rank to the lowest. Officer ranks are noted as Unrestricted Line Officers[a] (ULOs), Limited Duty Officers[b] (LDOs), and Warrant Officers[c] (WOs). Those MOSs which are no longer being awarded[d] are generally kept active within the Marine's service records to allow Marines to earn a new MOS and to maintain a record of that Marine's previous skills and training over time. All MOSs entered into the Marine Corps Total Force System (MCTFS) electronic service records will populate into DoD manpower databases, and be available upon request to all Marines through their Verification of Military Education and Training (VMET) portal, even when MOSs are merged, deactivated, or deleted from the current NAVMC 1200 bulletin, or from MCTFS.

Note: All listed MOSs are PMOS, unless otherwise specified.

Types of MOSs

There are three categories of MOSs:

There are six types of MOSs, divided into primary MOSs and non-primary MOSs. Primary MOSs are of three types:

There are also three types of non-PMOSs:

Reporting MOSs and billet designators are special MOSs:

Relationship of MOS to promotions

Officers are selected for promotion for their potential to carry out the duties and responsibilities of the next higher grade based upon past performance as indicated in their official military personnel file. Promotions should not be considered a reward for past performance, but as incentive to excel in the next higher grade. Officers are not strictly promoted based upon their MOS; all MOS carried by an officer are considered during the selection board process.

Enlisted Marines are promoted based upon their Basic MOS, or their PMOS if one has been earned, not their AMOS, FMOS, NMOS, or EMOS, although upon consideration by a selection board for promotion to Staff Sergeant (E-6) and above, the Board Members will be able to view evidence of other MOSs in the service records of the Marine.[5]
