The term MOS refers to Marine Occupational Specialty, and it's followed by a code of four numbers that identify a Marine's job, duties, title, and responsibilities. MOS 0844 designates what was once called the Field Artillery Fire Control Man, but this title was changed in 2016.

The position is now called the Field Artillery Fire Control Marine. After the Pentagon's 2015 decision to allow women to engage in front-line combat, the Secretary of the Navy determined that job titles within the Marines should be gender-neutral. The "0844" designation otherwise remained the same, but it was now titled in such a way as to indicate that the position could be held by either a man or a woman.

This is a primary MOS (PMOS), and the range rank is from sergeant to private.

Duties and Responsibilities 

Field Artillery Fire Control Marines perform duties essential to the delivery of accurate artillery fire, including position survey and fire direction computation. Typical responsibilities of the Field Artillery Fire Control Marine include preparation of fire control equipment for movement and operation, as well as performance of detailed survey operations.

These Marines also typically perform preventive maintenance. They perform routine testing on equipment and are authorized to make minor repairs to survey and fire control equipment. They operate field communications equipment, as well as constructing cannon battery databases.

Field Artillery Fire Control Marines can also be charged with constructing regiment, battalion, and Transaction Processing Performance Council (TPC) databases and maintaining data communications. They might construct data distribution.

Fire control computation includes the use of computer equipment systems, plotting survey data on firing charts. It includes determination of target coordinates, as well as the conversion to target coordinates and observer's reports into firing data and commands.

A complete listing of all duties and tasks associated with MOS 0844 is included in MCO 3501.26A, the "Artillery Unit Training and Readiness (T and R) Manual."

Job Requirements and Qualifications

MOS 0844 is assigned upon completion of formal schooling. Upon promotion to staff sergeant and the appropriate formal school, the 0844 will be designated MOS 0848. This MOS will be retained as an additional MOS.

Applicants for MOS 0844 must possess a GT score of at least 105, and higher is preferred. They must complete the Field Artillery Fire Control Marine Course and have a secret security clearance or be eligible for one. They must be U.S. citizens.
