CheckMyRegs answers one question — is this regulation current? — for every military branch at once. It indexes 15,866 publications from the official publishing portals and shows each pub's date, status, and official link, plus cross-branch comparisons of the regs people actually argue about (grooming, PT, leave, awards).
It is an unofficial index, not a mirror of publication text and not legal or official guidance. It is not affiliated with, endorsed by, or an official product of the Department of Defense or any military service. The controlling copy of any publication is the one on its official portal — always verify there before citing guidance in an official product.
Deep Air Force tooling (supplement trees, OSHA cross-references, paragraph-level answers) lives at our sister site CheckMyAFI.
