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.
