Every branch organizes its jobs differently and uses its own name for them — the Army and Marine Corps use a Military Occupational Specialty (MOS), the Navy and Coast Guard use ratings, and the Air Force and Space Force use the Air Force Specialty Code (AFSC). They all describe the same idea: the specific role you would train for and do.
This index links to the per-branch job listings so you can explore the roles each service offers and see how they are grouped. Pick a branch below to drill into its specialties.
Which jobs you can actually pursue depends on your ASVAB line scores meeting each role's composite minimum, along with branch needs and the rest of your eligibility. Think of the listings as tiers of options to research, not a list of guarantees.
