Your pin-on equivalent, in federal IT. — Army / Navy / Air Force / Marine Corps, E-3 through E-9 and O-1 through O-5, mapped to GS-5 → GS-13 with base and five locality pay areas.

If you're an E-3 through E-9 (or an O-1 through O-5 officer, for completeness) reading this on terminal leave, this is the comparison a GS-2210 HR specialist will quietly run on your résumé when your packet hits USAJOBS. Pick your service tab — Army, Navy, Air Force, or Marine Corps — read across the rank, the GS grade a federal HR reviewer will most often map it to, the Step 1 base pay the announcement carries, and the locality-adjusted figure you'll see in Washington–Baltimore–Arlington (DC/NCR), the SF Bay, New York, LA, or Seattle once you interview into a high-cost duty station.
