DMOS is an abbreviation for Duty Military Occupational Specialty. Since any individual can obtain multiple job specialties, DMOS is used to identify what their primary job function is at any given time. MOSQ is an abbreviation for Military Occupational Specialty Qualification. An individual is not MOSQ’d until they have completed and passed all required training for that MOS.

Army enlisted personnel

The MOS code (MOSC), consisting of nine characters, provides more defined information than a soldier's MOS. It is used by automated management systems and reports. The MOSC is used with active and reserve records, reports, authorization documents, and other personnel management systems.

The elements of the MOSC are as follows:
  • First three characters: The MOS. The first two characters are always a number, the third character is always a letter. The two-digit number is usually (but not always) synonymous with the Career Management Field (CMF). For example, CMF 11 covers infantry, so MOS 11B is "Rifle Infantryman". Among the letters, "Z" is reserved for "Senior Sergeant" (E-8), such that 11Z is "Infantry Senior Sergeant".
  • The fourth character of the MOSC represents skill level (commensurate with rank and grade):
    • 0 is used to identify personnel undergoing training for award of a primary MOS (PMOS).
    • 1 identifies a Private
      Private (rank)
      A Private is a soldier of the lowest military rank .In modern military parlance, 'Private' is shortened to 'Pte' in the United Kingdom and other Commonwealth countries and to 'Pvt.' in the United States.Notably both Sir Fitzroy MacLean and Enoch Powell are examples of, rare, rapid career...

  • Fifth character: A letter or number and a special Qualification identifier (SQI). It may be associated with any MOS unless otherwise specified. Soldiers without any special SQI are assigned the SQI "O" (oscar), often confused as a zero.
  • Sixth and seventh characters: An additional skill identifier (ASI). They are an alphanumeric combination and may only be associated with specified MOSs, although in practice some ASIs are available to every MOS (e.g. ASI P5 for "master fitness trainer"). Soldiers without any ASIs are assigned the default ASI "00" (zero-zero).
  • Eighth and ninth characters: Two-letter requirements and qualifications which are a language identification code (LIC). Soldiers without a language skill are assigned the default LIC "YY" (Yankee-Yankee). LIC codes can be found in AR 611-6.

MOSC for E-8 and above

When an enlisted soldier is promoted from Sergeant First Class to Master Sergeant in most career types, that soldier will be reclassified administratively to the "Senior Sergeant" of their Career Management Field. For example, a combat engineer (MOS 21B, part of CMF 21) is promoted from Sergeant First Class to Master Sergeant. That soldier is reclassified administratively from MOS 21B to MOS 21Z "Engineer Senior Sergeant"). An example of when this conversion occurs at the MSG to SGM level is the 68 (formerly the 91) CMF. In this case, the Soldier becomes a 68Z at the SGM level, not the MSG level.
When promoted from Master Sergeant or First Sergeant or Sergeant Major to Command Sergeant Major, that soldier will be reclassified administratively from their previous "Senior Sergeant" MOS to the MOS 00Z (zero-zero-zulu), "Sergeant Major".

Army warrant officers

 are sometimes specialized technicians and systems managers, and were not originally assigned to traditional arms or services of the Army. Approximately 50% of warrant officers are rotary wing aviators (helicopter pilots), and can be appointed directly from civilian applicants or within the service, regardless of previous enlisted MOS. The remaining 50% are technicians appointed from experienced enlisted soldiers and NCOs in a "feeder" MOS directly related to the warrant officer MOS.

During 2004, all Army warrant officers began wearing the insignia of their specialty's proponent branch rather than the 83-year old "Eagle Rising" distinctive warrant officer insignia. The following year a revision of Commissioned Officer Professional Development And Career Management integrated Warrant Officer Career Development with the Officer Career Development model. In practice, warrant officer MOSC are very similar to enlisted codes except they begin with three digits instead of two before the first letter, and do not have a "skill level" identifier. They are then followed by the SQI, ASI, and SLI as an enlisted MOS would.

Army commissioned officers

Commissioned officers' occupational codes are structured somewhat differently. A newly commissioned Army officer first receives a "career branch". This is similar to the career management field of the enlisted personnel. Career branch numbers range from 11 to 92. For example: 13 for Field Artillery, 19 for Armor/Armored Cavalry and 92 for Quartermaster. Within each occupational field, there are usually several codes available. Within Armor (Branch 19) there are 3 specialties available: 19A (Armor, General), 19B (Armor), and 19C (Cavalry). After an officer's fifth or sixth year of service, he or she may receive a "functional area" designation. More specific than a career branch, this is a specific skill set that the officer is proficient in. For example, an artillery officer who has had schooling in communications and public speaking could end up with a functional area in public affairs (FA46).

Marine Corps

The U.S. Marine Corps begins by separating all jobs into "occupational fields" (OccFld), in which no distinction is made between officers and enlisted Marines. The fields are numbered from 01 to 99 and include general categories (Infantry, Logistics, Public Affairs, Ordnance, etc.) that specific jobs fall under.

Each field contains multiple MOS's, each designated by a four-digit numerical indicator and a job title. For example, the infantry field (03) has nine enlisted classifications: Rifleman (MOS 0311
MOS 0311
MOS 0311 is the United States Marine Corps Military Occupational Specialty code for Rifleman. It is the primary infantry MOS for the Marine Corps.-General information:...

MOS 0341 is the United States Marine Corps Military Occupational Specialty for Mortarman.-General information:The mortarman in the Marine Corps infantry is the mobile support to the rifleman on the front lines. They utilize the M252 81mm mortar and the M224 60mm mortar systems...

), Assaultman (MOS 0351), Antitank Assault Guided Missileman (MOS 0352), and Infantry Unit Leader (MOS 0369

).

Each of the jobs have authorized ranks associated with them. For example, anyone ranking from Private to Sergeant can be a Rifleman (0311), but only Marines ranking from Staff Sergeant to Master Gunnery Sergeant can be an Infantry Unit Leader (0369).

Duties and tasks are identified by rank because the Marine Corps MOS system is designed around the belief that increased duties and tasks accompany promotions. The first two digits designate the field and, the last two digits identify the promotional channel and specialty.

For example, the MOS 0311 indicates that it is in Occupational Field 03 (Infantry) and designates the "Rifleman" (11) MOS. For warrant officers, the MOS 2305 indicates that it is in Occupational Field 23 (Ammunition and Explosive Ordnance Disposal) and designates the "Explosive Ordnance Disposal Officer" (05) MOS. For officers, the MOS 0802 indicates that it is in Occupational Field 08 (Field Artillery) and designates the "Field Artillery Officer" (02) MOS.

Commissioned Officer Designators

The Navy Officer "Designator" is similar to an MOS but is less complicated and has fewer categories. For example, a Surface Warfare Officer with a regular commission has a designator of 1110; a reserve officer has an 1115 designator. A reserve surface warfare officer specializing in Nuclear training (i.e., Engineer on a carrier) has a designator of 1165N. Navy officers also have one or more 3-character Additional Qualification Designators (AQD) that reflect completion of requirements qualifying them in a specific warfare area or other specialization. In some senses this functions more like the MOS in other services. An officer with the Naval Aviator designator of 1310 might have an AQD of DV3, SH-60F carrier
