DD Form 509 is a Department of Defense form, not a service form: Inspection Record of Prisoner in Segregation, used to Inspection Record of Prisoner in Segregation. The DD prefix is the operative fact. It means one blank serves every military department — Army, Navy, Air Force, Marine Corps, Space Force, Coast Guard under Defense jurisdiction — plus the defense agencies and combatant commands. No branch variant exists.
Requirement traces to not stated; the form belongs to not stated. Everything about schedule sits below that in local instruction, which is where to ask if a date matters.
Use not stated, status not stated. Older printings circulate widely and lose their currency Department-wide the moment a new edition issues.
Formats: PDF. Length unknown pages, approximately unknown entries. Pick on the basis of how you will complete it.
Take the fillable pdf unless you have a reason not to. Fillable means the boxes are real fields that accept typed text and retain it in the file. Printable means a flat blank — no fields, printer and pen only. The difference is not cosmetic: one produces a record that reproduces cleanly through scanning and forwarding, the other depends on penmanship.
Xfdl needs IBM Lotus Forms Viewer or a compatible client — a pdf reader will not open it. The format was the Defense standard for electronic forms across the Department for years, which is why it persists in DD distribution long after most users moved to pdf.
Nothing costs anything here. Work in a full desktop pdf application rather than a browser preview; field behaviour in browsers is unreliable.
Verify the edition before the first keystroke. The date on the form face should read not stated. If it does not, discard the file. Field numbering shifts between editions, and on a DD form the new layout reaches every receiving office in every service at once — there is no lag during which the old version is still normal somewhere.
Sequence matters. Identification precedes content, content precedes certification, because the lower half of a form is generally conditioned on the upper half.
Mark inapplicable items N/A rather than leaving white space. Use the date format the form specifies. This matters more on Department forms than on service forms: the record may be reviewed by personnel outside your branch who share none of your office conventions.
Read the Privacy Act Statement before entering identifiers, not after. Four facts are in it: authority, purpose, routine uses, consequence of declining. Its placement ahead of the data fields is deliberate.
Signature comes after everything else and must be a signature: pen, or a credentialed digital signature via Common Access Card. Typing does not qualify. Add the date at the same moment.
Review for the usual: old edition, blank required fields, illegibility on reproduction, date format, signature and date. Unclear entries — read the form face, then not stated; the directive prevails.
Submit to the office named in not stated or in local instruction; retain a duplicate before it leaves. Joint routing often sends a DD form across organizational boundaries, and tracing one afterward is not a same-day matter.
Related forms are found by number alone. The DD sequence is one unified Department-wide series, so a cited number resolves to exactly one document with no branch qualifier needed.
Do not read across from a service number. DA numbering is Army-specific under an Army proponent; DD numbering is Department-wide under not stated or an equivalent Department office. The sequences are unrelated, so identical digits in each identify two different documents. Read the prefix, not the digits.
Three drivers of revision: directive reissue, altered collection requirements, updated statutory notice text. No notification accompanies any of them, so download fresh and confirm not stated rather than reusing an archived file.
What is here is the blank form and a description of it. What is not here is legal guidance or any assurance about a particular filing — this page is not the issuing authority and does not speak for one. Those questions go to not stated, to your servicing administrative office, or to the authority identified in not stated.
