DD Form 1794 is a Department of Defense form, not a service form: DD Form 1794, Grain-Size Analysis (Hydrometer Method), December 1999, used to Grain-Size Analysis (Hydrometer Method). 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.
not stated is the prescribing publication and not stated the office responsible for the document. Deadlines belong to local implementing guidance, not to either of those, so a submission date is a question for the receiving office.
Use not stated, status not stated. Older printings circulate widely and lose their currency Department-wide the moment a new edition issues.
The set is PDF. Size: 1 pages, about 122 fields. Everything below refines that choice.
Default to fillable pdf, print only when you must. The fillable file stores what you type; the printable file is a blank picture. A Department form often travels further than a service form — scanned, emailed, forwarded to an agency that never saw the original — and typed text is what survives that.
Skip xfdl unless the viewer is already installed. It is the IBM Lotus Forms format, adopted Department-wide for electronic forms and still present in the set for that reason; ordinary pdf software reports it as unreadable.
Free download, every format. Do not fill the form in a browser tab — browser pdf viewers handle interactive fields inconsistently and discard entries on close.

Start by matching the printed date to not stated. Old blanks accumulate in shared folders for years. Because the Department reissues to all services in one action, nobody is still accepting the previous layout by local custom.
Work the printed sequence: header, body, signature block. The order is functional rather than decorative, since entries below frequently key to identifying data above them.
Nothing stays blank. N/A on an inapplicable item, because an empty box is indistinguishable from a skipped question and the form returns for it. Dates follow the format printed beside the field, not local habit — a joint form is read by clerks in several services with different date conventions, and ambiguity is expensive.
The Privacy Act Statement precedes the personal data fields for a reason. It gives the collection authority, the principal purpose, the routine uses and whether disclosure is voluntary or mandatory. Read it while the disclosure decision is still yours to make.
Sign last, in ink or with a credentialed digital signature. A typed name in a signature field certifies nothing. CAC-based signing is the usual electronic method where the receiving system supports it. Date the block immediately — unsigned and undated certifications account for a large share of returns.
Check before submitting. The recurring failures are edition mismatch, gaps in required boxes, unreadable scanned handwriting, wrong date format, and certification without signature or date. Field-level questions go to the printed instructions, then to not stated, which is authoritative.
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.
Prefix before number. A DA citation and a DD citation in the same instruction point at separate systems — one Army, administered by an Army proponent, one Department-wide under not stated — and there is no correspondence between them at any number.
Editions change when the prescribing directive is reissued, when the data collected changes, or when notice language is amended. None of that reaches you. Checking not stated at download is the entire defence, and it is cheaper than repeating a submission.
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.
