The United States Marine CorpsMilitary 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.

• Maintenance Engineer Salary
• Mutoh Maintenance Engineer Assistant Marines Salary
• Mutoh Maintenance Engineer Assistant Marines Training

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.

What Marine Engineers and Naval Architects Do. Marine engineers and naval architects design, build, and maintain ships, from aircraft carriers to submarines and from sailboats to tankers. Marine engineers are responsible for the internal systems of a ship, such as the propulsion, electrical, refrigeration, and steering systems. Marine Corps Engineer School. The morning was filled with various activities to include: a fartlek run with obstacles, dry bounce-house, bounce-house with water slide, Indoor Simulated Marksmanship Trainer (ISMT), static display of equipment, and water soccer. In the afternoon Marines had the opportunity to take their children to their work areas. Assistant Chief Maintenance and Engineering Officer Page 2 EXAMPLES OF DUTIES – Duties may include, but are not limited to, the following: 1. Assumes full management responsibility for all assigned infrastructure assets, which may include single or multiple categories of asset types.

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.

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 as 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.
6. Billet requirements identified by a MOS (BMOS) must include a training concept when established that builds an inventory of Marines prepared for assignment to the BMOS. A concept that awards a MOS after successfully serving in a billet is not valid.

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.

• 1Types of MOSs

Types of MOSs[edit]

There are three categories of MOSs:

• Occupational Fields 01-79 (Regular OccFlds) – Occupational Fields that contain all types of MOSs related to a specific occupational field.
• 80XX (Miscellaneous Requirement MOSs) – These are MOSs that do not fit into a regular OccFld but are used on the Marine Corps Table of Organization (T/O).
• 90XX (Reporting MOS) – These MOSs do not exist on the USMC T/O. They are used to meet Department of Navy and Department of Defense reporting requirements.^[2]

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

• Basic MOS – Entry-level MOSs required for entry-level Marines (both officers and enlisted) or others not yet qualified by initial skills training. In addition, when a Reserve Component (RC) Marine transfers to a new unit and does not possess the MOS required for the billet filled, they will be assigned a Basic MOS as Primary MOS until the completion of required formal school training or is otherwise certified to be MOS qualified, and the previous PMOS will be retained but become an Additional MOS. Promotions for enlisted Marines will be based upon their Basic MOS, or if qualified for a PMOS, then upon their PMOS, never on an AMOS.
• Primary MOS (PMOS) – Used to identify the primary skills and knowledge of a Marine. Only enlisted Marines, Warrant Officers, Chief Warrant Officers, and Limited Duty Officers are promoted in their primary MOS. Changes to an Active Component Marine's PMOS without approval from CMC (MM) and changes to a RC Marine's PMOS without approval from CMC (RA) are not authorized. Promotions for enlisted Marines will be based upon their Basic MOS, or if qualified for a PMOS, then upon their PMOS, never on an AMOS.
• Additional MOS (AMOS) – Any existing PMOS awarded to a Marine who already holds a PMOS. Example: after a lateral move to a new job, a Marine's previous PMOS becomes an AMOS and is normally retained in the Marine's service records for historical purposes and manpower management. Marines are not promoted in an AMOS.^[2]

There are also three types of non-PMOSs:

• Necessary (NMOS) – A non-PMOS that has a prerequisite of one or more PMOSs. This MOS identifies a particular skill or training that is in addition to a Marine's PMOS, but can only be filled by a Marine with a specific PMOS. When entered as a requirement into the TFSMS, a billet bearing a Necessary MOS must identify a single associated PMOS even if several PMOSs are acceptable prerequisites.
• Free (FMOS) – Non-PMOS that can be filled by any Marine regardless of Primary MOS. A Free MOS requires skill sets unrelated to primary skills.
• Exception (EMOS) – Non-PMOS that is generally a FMOS, but includes exceptions that require a PMOS.^[2]

Reporting MOSs and billet designators are special MOSs:

• Reporting MOSs – designated in the 90XX OccFld, but are not found on any USMC T/O as a requirement to fill any billet. They exist solely to capture skills and training that meet Department of Navy and Department of Defense reporting requirements.
• Billet MOSs (BMOS) – The MOS listed on USMC T/Os for each billet within the organization, usually PMOS, but also NMOS, FMOS, EMOS, or Billet Designators. Some billets will include notes about acceptable alternate MOSs, such as a BMOS of 0402 (Logistics Officer) that notes an 3002 (Supply Officer) is an acceptable staffing substitute for that billet.
• Billet Designators – An FMOS requirement indicator, listed on USMC T/Os as a BMOS that can be filled by any Marine of the appropriate grade that is included in the MOS definition (e.g., MOS 8007 Billet Designator-Unrestricted Ground Officer (I) FMOS). Normally, FMOS as a skill designator cannot be a BMOS in the TFSMS.^[2]

Relationship of MOS to promotions[edit]

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.^[4]

Seafaring is a tradition which encompasses a variety of professions and ranks. Each of these roles carries unique responsibilities which are integral to the successful operation of a seafaring vessel.^[1] A ship's crew can generally be divided into four main categories: the deck department, the engineering department, the steward's department, and other. The reasoning behind this is that a ship's bridge, filled with sophisticated navigational equipment, requires skills differing from those used on deck operations – such as berthing, cargo and/or military devices; which in turn requires skills different from those used in a ship's engine room and propulsion, and so on.

However do note that the following is only a partial listing of professions and ranks. Ship operators have understandably employed a wide variety of positions, given the vast array of technologies, missions, and circumstances that ships have been subjected to over the years.

There are some notable trends in modern or twenty-first century seamanship. Usually, seafarers work on board a ship between three and six years. Afterwards they are well prepared for working in the European maritime industry ashore.^[2] Generally, there are some differences between naval and civilian seafarers. One such example is nationality on merchant vessels, which is usually diverse and not identical like on military craft. As a result, special cross-cultural training is required – especially with regard to a lingua franca.^[3] Another notable trend is that administrative work has increased considerably on board, partly as an effect of increased focus on safety and security. A study shows that due to this development certain skills are missing and some are desired, so that a new degree of flexibility and job sharing has arisen, as the workload of each crew member also increases.^[4]

Modern ship's complement[edit]

Captain[edit]

The captain or master is the ship's highest responsible officer, acting on behalf of the ship's owner. Whether the captain is a member of the deck department or not is a matter of some controversy, and generally depends on the opinion of an individual captain. When a ship has a third mate, the captain does not stand watch.

The captain is responsible for the day-to-day affairs of the ship as he/she is in command. It is his/her responsibility to ensure that all the departments under him/her perform to the requirements. The captain represents the owner and hence is called 'master'.

Deck department[edit]

Deck officers[edit]

Deck officers are licensed mariners that are responsible for the navigation and safe passage of the ship.

Chief mate[edit]

The chief mate is the head of the deck department on a merchant vessel, second-in-command after the ship's Master. The Chief mate's primary responsibilities are the vessel's cargo operations, its stability, and supervising the deck crew. The mate is responsible for the safety and security of the ship, as well as the welfare of the crew on board. The chief mate typically stands the 4–8 navigation watch as OICNW (officer in-charge of the navigational watch), directing the bridge team. Some crews have additional Third mates, which allow the Chief mate to not stand navigational watch, and focus more on cargo and deck operations. Additional duties include maintenance of the ship's hull, cargo gears, accommodations, life saving appliances and firefighting appliances. The chief mate also trains the crew and cadets on various aspects like safety, firefighting, search and rescue, and various other contingencies. The chief officer assumes command of the whole ship in the absence or incapacitation of the master.

Second mate[edit]

The second mate is a qualified OICNW watch stander, directing the bridge team and navigating the ship. The Second mate is the 3rd most experienced deck department officer after the Captain/Master and Chief mate. The Second mate's primary duty is navigational, which includes updating charts and publications, keeping them current, making passage plans, and all aspects of ship navigation. The Second mate's other duties may include directing line handlers, cargo watches, directing anchor detail and training and instructing crew members.

Third mate[edit]

The Third officer is a qualified OICNW watch-stander, junior to the Second Mate. When on navigational watch, the Third mate directs the bridge team, maneuvering the vessel, keeping it safe and on track. The Third mate's primary duty is matters of safety, inspecting gear lockers, lifeboats, and all equipment onboard ensuring that it is safe and operational. Other duties include directing line handlers, cargo watches, directing anchor details and training and instructing crew members. He is normally the part of the Command team during emergencies and drills.

Deck cadet[edit]

A Deck Cadet or Trainee Navigational Officer or Nautical Apprentice is an apprentice who has to learn the basic duties of a deck officer onboard a ship. Deck cadets after sufficient sea time and exams attain certificate of competency of OICNW.

Deck ratings[edit]

Mariners without a certificate of competence are called ratings. They assist in all other tasks that can arise during a voyage. This includes for example, mooring, cleaning of the ship and its holds and repairing broken lines and ropes. These are physically challenging jobs and have to be done regardless of the weather.^[2]

Boatswain[edit]

The boatswain is the highest ranking unlicensed (rating) in the deck department. The boatswain generally carries out the tasks instructed by the chief mate, directing the able seaman and ordinary seaman. The boatswain generally does not stand a navigational watch.

Able seaman[edit]

An able seaman (AB) works under the boatswain, completing tasks such as working mooring lines, operating deck gear, standing anchor details, and working cargo. An able seaman also stands a navigational watch, generally as a lookout or helmsman.

Ordinary seaman[edit]

The lowest ranking personnel in the deck department. An ordinary seaman (OS) generally helps out with work that able seamen do. Other tasks include standing lookout, and generally cleaning duties.

Engine department[edit]

Engineering officers[edit]

The engineers are also called technical officers. They are responsible for keeping the ship and the machinery running. Today, ships are complex units that combine a lot of technology within a small space. This includes not only the engine and the propulsion system, but also, for example, the electrical power supply, devices for loading and discharging, garbage incineration and fresh water generators. Also they are commonly considered a high officer in ranking in the ship.^[2]

Chief engineer[edit]

The chief engineer on a merchant vessel is the official title of someone qualified to oversee the engine department. The qualification for this position is colloquially called a 'Chief's Ticket'.

The Chief Engineer, commonly referred to as 'The chief', or just 'chief', is responsible for all operations and maintenance that have to do with all machinery and equipment throughout the ship. They may be paid on par with the captain, and holds the same rank as the captain, although he is never responsible for the action of ship. The chief engineer cannot assume command and the command always rests with the Captain of the ship, unless it is clearly mentioned within the safety management system.^{[citation needed]}

Second engineer[edit]

The second engineer or first assistant engineer is the officer responsible for supervising the daily maintenance and operation of the engine department. He or she reports directly to the chief engineer.^{[citation needed]}

Third engineer[edit]

The third engineer or second assistant engineer is usually in charge of boilers, fuel, auxiliary engines, condensate and feed systems, and is the third most senior marine engineer on board. Depending on usage, 'the Second' or 'the Third' is also typically in charge of fueling (a.k.a. bunkering), granted the officer holds a valid Person In Charge (PIC) endorsement for fuel transfer operations.^{[citation needed]}

Fourth engineer[edit]

The fourth engineer or third assistant engineer is junior to the second assistant engineer/third engineer in the engine department.

Engine ratings / unlicensed[edit]

Motorman[edit]

The motorman is an unlicensed member of the engine department, with more experience than an Oiler.

Oiler[edit]

Maintenance Engineer Salary

The oiler is an unlicensed member of the engine department, with more experience than a Wiper.

Wiper[edit]

The wiper is an unlicensed member of the engine department, usually with the least experience.^{[citation needed]}

Mutoh Maintenance Engineer Assistant Marines Salary

Electro-technical department[edit]

Electro-technical officer[edit]

The electro-technical officer sometimes referred to as the electrical engineer is in charge of all the electrical systems on the ship. The electrical engineer is one of the most vital positions in the technical hierarchy of a ship and engineer is responsible for their assigned work under the chief engineer’s instructions.

Unlike engineers the ETO does not carry out an assigned engine room 'watch' instead they are normally on call 24 hours a day and generally work a daily shift carrying out electrical and electronic maintenance, repairs, installations and testing.

Some shipping companies do not carry electrical officers on their ship to cut down the manning cost, and the electrical duties are carried by an engineer. This is usually the third engineer. However, many companies realized that electrical and electronic system requires some extra attention and therefore require an expert to attend them. This is especially true on diesel electric ships or vessels equipped with systems such as dynamic positioning.

On larger vessels such as cruise ships, electrotechnical officers can have ranks within their profession, such position names include, lead ETO, 1st Electrician, chief electrical officer or chief electrical engineer. In this situation, the highest ranked electrotechnical officer will report directly to the chief engineer. On special class ships such as FPSOs the electrotechnical officer can sometimes earn nearly the same wage as a chief engineer due to the complexity of the electrical systems on the ship.

As the technology advances, more automation and electronic circuits are replacing conventional and electrical systems. The International Maritime Organisation (IMO) amended STCW 95 (also known as the Manila Amendment) on June 25, 2010 to introduce the certified position of Electro-technical officer in place of Electrical officer.^{[citation needed]}

With advancements in satellite communications leading to the widespread adoption of the Global Maritime Distress and Safety System the old position of radio officer is far less common, although a U.S. Coast Guard license is still issued for it.^[5] Ship officers may be licensed by the Federal Communications Commission as GMDSS operators and electrical officers as GMDSS maintainers. Morse code has not been used on French ships since 1997^[6] and on U.S. ones since 1999^[7] However, an FCC certificate for radiotelegraphy may still be obtained.

Steward's department[edit]

Chief steward[edit]

The chief steward directs, instructs, and assigns personnel performing such functions as preparing and serving meals; cleaning and maintaining officers' quarters and steward department areas; and receiving, issuing, and inventorying stores. The chief steward also plans menus; compiles supply, overtime, and cost control records. The steward may requisition or purchase stores and equipment. Additional duties may include baking bread, rolls, cakes, pies, and pastries.

Chief cook[edit]

The chief cook is the senior unlicensed crew member working in the steward's department of a ship. His position corresponds to that of the Boatswain in the deck department, the pump man in an oil tanker, and the electrician (but not ETO) in the engine department of a container ship or general cargo ship. He is the equivalent to a chief petty officer in the Navy.^{[citation needed]}

The chief cook directs and participates in the preparation and serving of meals; determines timing and sequence of operations required to meet serving times; inspects galley and equipment for cleanliness and proper storage and preparation of food.^{[citation needed]}

Royal Navy historical ship's complement[edit]

The Captain was a commissioned officer naval officer in command of a ship and was addressed by naval custom as 'captain' while aboard in command, regardless of the officer's actual rank.

Wardroom officers[edit]

The Lieutenants were commissioned officers immediately subordinate to the captain. Lieutenants were numbered by their seniority within the ship, so that a frigate (which was entitled to three lieutenants) would have a first lieutenant, a second lieutenant, and a third lieutenant. A first-rate was entitled to six lieutenants, and they were numbered accordingly.

The 'Sailing Master' was a naval officer trained in and responsible for the navigation of a sailing vessel. The rank can be equated to a professional seaman and specialist in navigation, rather than as a military commander and was originally a warrant officer who ranked with, but after, the lieutenants and was eventually renamed to 'navigating lieutenant' in 1867.

The Captain of Marines was the commissioned office in command of the Royal Marines on the ship.

The Purser was the officer responsible for all administration and of supplies such as food and drink, clothing, bedding, candles, the purser was originally known as 'the clerk of burser'. Pursers received no pay but were entitled to profits made through their business activities. In the 18th century a purser would buy his warrant for £65 and was required to post sureties totalling £2,100 with the Admiralty.^[9] They maintained and sailed the ships and were the standing officers of the navy, staying with the ships in port between voyages as caretakers supervising repairs and refitting.^[10]

The Surgeon was the medical officer of the ship. Surgeons were ranked by the Navy Board based on their training and social status.^[11] Surgeons were wardroom warrant officers with a high status, billeted along with the other officers in the wardroom.^[12] Surgeons were assisted by surgeon's mates, who after 1805 were called 'assistant surgeons'.^[13] The surgeon and his mates were assisted by boys, who were called 'loblolly boys', named after the gruel commonly served in the sick bay.[7] A small number of doctors with a prestigious medical education were ranked as physicians; they would supervise surgeons on ships or run hospitals on shore.^[14]

The Chaplain led the ship's religious services. As an ordained minister, his social status meant he was made an officer.

Standing officers[edit]

The Gunner was the warrant officer in charge of the ships's naval artillery and other weapons. He supervised the Armourer, the Gunners mate and the Yeoman of the Powder room.

The Boatswain (/ˈboʊsən/), bo's'n, bos'n, or bosun, was the warrant officer of the deck department. As deck crew foreman, the boatswain planned the day's work and assigned tasks to the deck crew. As work was completed, the boatswain checked the completed work was done correctly. He supervised the Ropemaker, the Boatswain's mate and the Sailmaker.

The carpenter was the warrant officer who was responsible for the maintenance and repair of the wooden components of the ship. He supervised the Caulker, the Carpenter's mate and the Master-at-arms.

Cockpit mates[edit]

Originally, a master's mate was an experienced petty officer, who assisted the master, but was not in line for promotion to lieutenant.^[15] By the mid-eighteenth century, he was far more likely to be a superior midshipman, still waiting to pass his examination for lieutenant or to receive his commission, but taking rather more responsibility aboard ship. Six master's mates were allowed on a first rate, three on a third rate, and two on most frigates.^[16]

Senior petty officers[edit]

A Midshipman was an apprentice officer who had previously served at least three years as a volunteer, officer's servant or able seaman, and was roughly equivalent to a present-day petty officer in rank and responsibilities. After serving at least three years as a midshipman or master's mate, he was eligible to take the examination for lieutenant. Promotion to lieutenant was not automatic, and many midshipmen took positions as master's mates for an increase in pay and responsibility aboard ship.

The Clerk was a literate worker who did administrative work on the ship.

The Armourer maintained and repaired the smaller weapons on the ship.

The Caulker maintained and repaired the caulking of the ship's hull.

The Ropemaker made, maintained and repaired ropes on board.

The 'Master-at-arms' was a naval rating, responsible discipline aboard ship, assisted by Corporals.

Petty officers[edit]

The Yeoman of the Sheets was in charge of the rope store. Given that the ship was rarely dry inside and the ropes rotted when wet, preserving the rope was a major problem.^[17]
