Military MOS Lists

Home » Careers » Military MOS Lists

An MOS, or military occupational specialty, involves the breathtakingly wide range of jobs carried out by members of the United States armed forces — more than10,000 different specialties covering a vast array of skills, interests, opportunities, and levels of responsibility.

An MOS can be absolutely precise, a meticulous description of the skills required and job to be performed. Others are purposely generalized.

Moreover, while every MOS has a military function, not every occupation is military-specific. MOS designations can include civilian workplace equivalents, such as administration, engineering, construction, information technology, communications, logistics, maintenance, healthcare, and so on

How Are Military Occupational Specialty Lists Used?

MOS lists are used to define and detail jobs/specialties in the armed forces. Specialties that are similar or related are gathered into branches and categorized within various Career Management Fields. Each job is given a unique designation; related specialties within a category get the same two numbers, followed by a letter assigned to a particular specialty.

Training for each job is as specialized as the specialty itself. Opportunities for advancement are available in each, as are opportunities to move laterally, change to other MOS ratings, and expand skills through training.

Navy Rating List

When is an MOS not an MOS? When it goes by the title “rating,” which is how the U.S. Navy classifies its occupational branches and individual jobs. The Navy’s 93 ratings are organized into groups known as communities, such as aviation, medical, security, submarine, surface operations, nuclear, administration, and so on.

Ratings identify general enlisted occupations consisting of specific skills and abilities. Specialty badges are assigned to each naval rating, and worn on the left sleeve of the uniform.


The Navy’s ratings include:


The Administration Community provides oversight and direction for the Navy as a whole. Administration jobs include:

  • Legalmen (LN) (Paralegals) provide legal assistance to fellow sailors and prepare records for proceedings such as courts-martial and courts of inquiry. They also assist personnel in filing claims and conducting investigations.
