DD Form 2688 is a Department of Defense form, not a service form: DD Form 2688, Building Elements Cost Worksheet, February 1994, used to Building Elements Cost Worksheet. 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.
Authority: not stated prescribes it, not stated maintains it. Those two names settle most disputes about why the form is being asked for. Local commands add timing on top; the requirement itself comes from above them.
Current edition is not stated, carried as not stated. Check that against any copy you already hold before doing anything else — Department-level revisions land everywhere simultaneously, so a stale file is stale across the whole Department.
Available: PDF, across 1 pages, roughly 102 fields.
All formats are free. One operational note: save the file locally and open it in a desktop reader. Browser-embedded viewers drop field properties and lose typed data without warning.

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.
Unclear entries — read the form face, then not stated; the directive prevails.
Send it as not stated or local guidance specifies. Save a copy. Cross-service and cross-agency routing is normal for Department forms, and a lost original outside your own organization is harder to chase down.
A number is a complete address in the DD series. Because the sequence is Department-level and not duplicated per service, there is nothing further to specify.
Where a procedure cites both a service form and a DD form, the two are unconnected. Service numbering answers to a service proponent, DD numbering to not stated or another Department office, and the two sequences were never aligned. Matching numbers mean nothing whatever.
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.
