You have arrived looking for DD Form 1794. Before you download, confirm this is the right document: Grain-Size Analysis (Hydrometer Method). Full title: DD Form 1794, Grain-Size Analysis (Hydrometer Method), December 1999.
Next, check the edition. You want not stated, currently carried as not stated by the publisher. Then confirm the form applies to you — this is a Department of Defense form, so you use it whether you serve in the Army, Navy, Air Force, Marine Corps, Space Force or Coast Guard under Defense jurisdiction.
After that, turn to timing. The requirement comes from not stated; the form is maintained by not stated. Local implementing instructions fill in the dates, so check with the office that will receive your copy.
Finally, decide how you will complete it. You can type into a fillable file or print a blank and write by hand, and the rest of this page walks you through both paths in order.
Begin at the top and move down. Enter your identifying data first, then the body of the form, then the signature block. The sequence is printed in that order because entries below frequently follow from entries above.
Before your first entry, look at the corner of the page and compare the printed date with not stated. If they do not match, stop and download again. Old copies circulate in shared drives for years, and a DD form is revised centrally for every service at once, so a superseded blank may not carry the fields your reviewer expects.
Work through the fields one at a time and leave nothing blank. When a box does not apply to you, write N/A rather than skipping it, so the reviewer can see you read the question. Follow the date format printed beside each date field instead of the one you normally use.
When you reach a Privacy Act Statement, read it before you continue. It tells you the legal authority for collecting your information, what the Department does with it, who else may see it, and whether you have to answer at all. That last point is worth knowing before you supply personal identifiers, not after.
Finish with the certification. Print the form and sign in ink, or apply a digital signature with your CAC if the receiving office accepts one. Do not type your name in the signature box and consider it done; that is a name, not a signature. Date the block immediately after signing.
Run a final pass over the form. The errors that send it back are the same ones every time: old edition, gaps in required fields, unreadable handwriting on a scan, non-conforming dates, no signature or no date.
For questions about a specific entry, check the form's own instructions, and if that does not settle it, open not stated. The directive controls where they differ.

Begin by choosing a file. Available here: PDF. Plan for 1 pages and about 122 entries.
You will not be charged for any of these; the whole set is free. Before you start entering data, save the file to your computer and open it there. Fields behave far more reliably in a desktop reader than in a browser preview.

Now that it is complete, send it where not stated or your local procedure says it goes. Before you do, make yourself a copy — scan it or save the file elsewhere. It costs you nothing and saves you the whole exercise if the original goes missing.
Should you need a related form, look it up by its number. The DD sequence is Department-wide, which makes your search simple: no service qualifier, no branch-specific variant to track down.
Be careful when a procedure pairs this form with a service form. Read the prefix, not just the digits. Service forms answer to a service proponent, while DD forms answer to not stated or an equivalent Department office, and the two sequences were never aligned. Grabbing the wrong prefix gets you a form that has nothing to do with your task.
Do not archive this file and reuse it in a year. Forms are reissued as directives are revised, as data requirements shift, and as statutory notice text is amended. Your protection is simple: download fresh each time and confirm the edition date.
One thing this page does not do: tell you whether your submission will be accepted. We publish the document and explain how to complete it, and that is where our role ends. Nothing here is legal advice. Take questions about eligibility, applicability or procedure to not stated, to your servicing personnel office, or to the office named in not stated.
