The official file for COMDTINST M1001.28D returns HTTP 404 when we checked on 2026-09-01. We have no publisher index for this series to say whether it moved or was withdrawn — only that the address on record no longer serves it. That is expected for a publication we record as not in the current catalog — portals remove the file once a publication leaves force. It is recorded here so the link does not simply fail in your hands.
Address on record: https://media.defense.gov/2021/Feb/09/2002579382/-1/-1/0/CIM_1001_28D.PDF. We check the link by requesting it, not by assuming it works.
Newest first. Dates are the publication dates in the official catalog. Earlier editions are kept because a copy stamped with one of them is a different document — this list is what we hold, not a claim to be complete.
