The Complete MOS Library

Scroll below to learn about Military Occupational Specialities (MOS's) 

The Marine Corps breaks each functional occupation into a parent occupational field, such as Logistics, Intelligence, Finance, Infantry, or Engineering. 

 

Each occupational field has a two-digit identifier. Each specific job, or occupational specialty, comes with two more digits after the occupational field that identify the MOS.

 

Officer MOS's will have a zero in the last two digits, while enlisted MOS's will not.
