Where this data comes from

Most of the data on this page comes from the Air Force Enlisted Classification Directory (AFECD) and recruiter TTMS readouts, which are no longer released publicly. Pulling it together and keeping it accurate takes real time, so I update these pages as often as I can.

Requirements do change between updates. Before you make any decisions, confirm the details with your recruiter. They always have the latest word.
