Every entry in the Defense records system exists because some decision needed a documented basis, and DD Form 453-1 is one of those instruments: Travel Order, created to Travel Order. The reason it carries a DD number rather than a service designation is structural — the Department maintains a single body of forms for matters that arise identically in every service, so that a record created in one component remains intelligible in another.
The practical effect of Department-level issue is interoperability. not stated establishes the requirement across the Defense enterprise; not stated keeps the document current for all of it. No service maintains its own variant, which means a completed record travels between components — service to agency, agency to joint command — and arrives in a format the receiving office already knows how to read.
The edition in force is not stated, carried by the publisher as not stated, and edition discipline is stricter on a Department form than most people expect, precisely because supersession happens everywhere at once. There is no interval during which one service still works from the previous layout while another has moved on.
The sequence printed on the form is the sequence in which a reviewer will read it, and the two should agree. Header data frames every entry below it; the substantive fields depend on that frame; the certification stands at the end because its whole function is to vouch for what came before. Entries made out of sequence commonly contradict entries made earlier.
Before the first entry, compare the date printed on the form face with not stated. This is not bureaucratic fussiness. Editions change field numbering, and a receiving office working from the current layout may look for information where your copy does not put it. On a Department form the exposure is wider than usual: your record may be reviewed by an office in another service entirely, one with no reason to remember what the previous edition looked like.
For an ambiguous field, read the form's own instruction, then not stated, which controls.
Download the form
The set published here is PDF, covering unknown pages with roughly unknown fields. More than one format survives because the Department serves users under very different conditions, from a desk with current software to a location where a printer is the only reliable output.
The difference between a fillable and a printable pdf is a difference in what the file contains. A fillable release carries an interactive layer: each box is a defined field with a name and a data type, and what you type is stored as data inside the document. A printable release has no such layer — it is an image of the page, and the only place your answers can go is onto paper. The distinction matters downstream, because a Department record often gets scanned and forwarded several times before it reaches its final file, and typed characters survive that chain in a way pen strokes do not.
Every format is free, as published government documents are. A note on tools, though — the interactive field layer that makes a fillable pdf useful is precisely the part browser viewers handle least reliably. Save the file, open it in a full pdf reader, and the fields behave as the form's designer intended.
Submission follows not stated and whatever local instruction supplements it. Make a copy before the original leaves. Department forms travel across organizational lines by design, and the administrative distance that makes them useful is the same distance that makes tracing a lost one difficult.
Cross-referenced documents are found by series and number, with nothing further required. That the DD sequence is unified across the Department means a cited number identifies one form and no other, which is the practical payoff of centralizing the numbering in the first place.
Procedures that touch both Department and service processes will cite forms from both sequences, and the coincidence of numbers between them is exactly that — coincidence. An Army proponent maintains the DA series for the Army; not stated or another Department office maintains the DD series for the whole Department. Two independent registries, two independent numbering runs, no correspondence at any value.
A form is downstream of the policy that requires it, and revision usually starts there: a directive is reissued, a collection requirement is altered, notice language is updated by statute. The form is republished as a consequence. Since none of that reaches individual users, an archived copy quietly becomes wrong, and verifying not stated each time you download is the whole remedy.
A word on what this page is. It distributes a published Department of Defense document and describes what the document contains and how it is completed. It is not the issuing authority, does not speak for one, and offers no legal advice; nothing written here determines whether a particular submission will be accepted, because that determination belongs entirely to the office receiving it. Questions of applicability, eligibility or procedure go to not stated, to your servicing personnel office, or to the office identified in not stated.
