Every entry in the Defense records system exists because some decision needed a documented basis, and DD Form 1191 is one of those instruments: Medical Oxygen Equipment, Warning Tag For Medical Equipment, created to Medical Oxygen Equipment, Warning Tag For Medical Equipment. 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.
This is why the arrangement matters to you rather than only to the archivists. not stated governs the form throughout the Department, with not stated as the responsible office, so the record you create is legible outside your own component. Joint assignments, agency details and cross-service transactions all depend on that: the paperwork does not have to be reconstructed each time it crosses a boundary.
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.
Work down the page in the printed order, and understand why the order exists. The identifying block establishes whose record this is and under what circumstances it arises. The body of the form then answers questions that are only meaningful once that context is fixed. The signature block comes last because a certification signed before the entries are complete certifies nothing.
Verify the printed edition against not stated first. Field structure shifts between editions, and the office that receives your record is reading the current one. That office may sit outside your service, which removes even the informal accommodation you might expect from a colleague who used the old version last month.
Where a specific field is genuinely unclear, the instructions printed on the form come first and not stated governs where the two do not agree.
Download the form
Formats available: none published here, across unknown pages and about unknown fields. That several formats coexist is a consequence of scale — the Department cannot standardize the software on every desk that needs this form, so it standardizes the document instead.
Two states of the same page circulate, and the reason is worth knowing. In the fillable pdf, the boxes are real fields holding real data; in the printable pdf, the boxes are drawings. Where a record will cross components — as Department records regularly do — the typed version is the safer artifact. Each scan, each forwarding, each reproduction costs handwriting a little legibility, and the office that finally files the record is rarely the office that received it first.
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.
It helps to see the DA and DD sequences as what they are: separate registries with separate custodians. One serves a single service under a service proponent, the other serves the Department under not stated or an equivalent office, and neither was ever indexed against the other. A number that appears in both systems points to two unrelated documents, which is why reading the prefix comes before reading the digits.
Understanding why editions change explains why checking them is not optional. Revision follows directive reissue, changes in what data is required, and amendments to mandatory notice text — decisions made at Department level and communicated through publication rather than notification. The file you saved does not update itself, so the edition date at download is what you rely on.
What you have here is the document and a description of it, which is a different thing from guidance. This page is not an organ of the Department, gives no legal or procedural advice, and makes no representation about the outcome of any filing; the offices that administer the requirement are the only ones positioned to answer that. Applicability, eligibility and procedural questions belong to not stated, to your servicing personnel office, or to the office designated in not stated.
