Frequently asked questions
Common questions about military job codes and this directory.
What is an MOS?
A Military Occupational Specialty (MOS) is a code that identifies a specific job in the U.S. military. The Army and Marine Corps use MOS codes, the Navy and Coast Guard use Ratings, the Air Force uses Air Force Specialty Codes (AFSCs), and the Space Force uses Space Force Specialty Codes (SFSCs). Each code maps to a distinct set of duties, skills, and career paths.
What branches does mos.directory cover?
mos.directory covers all six branches of the U.S. armed forces: Army, Navy, Air Force, Marine Corps, Coast Guard, and Space Force. Every branch uses a different naming convention for its job codes, but the directory normalizes them into a single searchable database.
What information is available for each specialty?
Each specialty page includes the official code and title, a plain-language description of duties, core skills, common certifications, civilian career paths (role families), training and development recommendations, and category classification. Data is sourced from official military publications and public occupational references.
How do I search for a military job code?
Use the directory page to search by code, title, or keyword. You can filter by branch and rank, then click any result to see the full specialty profile. The search works across all branches simultaneously, or you can narrow it to a single branch first.
What are civilian equivalents of military jobs?
Each specialty page lists civilian career paths, also called role families, that align with the military job's skills and experience. These help service members and veterans identify private-sector careers that match their training, and help employers understand what military candidates bring to the table.
Is mos.directory affiliated with the U.S. military?
No. mos.directory is an independent, free resource. It is not affiliated with, endorsed by, or sponsored by the U.S. Department of Defense or any branch of the military. Data is compiled from publicly available official military publications and occupational references.
