DD Form 2678 is a Department of Defense form, not a service form: DD Form 2678, Well Driller's Log, October 1993, used to Well Driller's Log. 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.
Requirement traces to not stated; the form belongs to not stated. Everything about schedule sits below that in local instruction, which is where to ask if a date matters.
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.
The set is PDF. Size: 2 pages, about 187 fields. Everything below refines that choice.
Fillable pdf is the default choice. Its boxes hold typed entries inside the document; the printable release is a static image of the same page with no interactive layer. Since DD forms routinely cross between services and agencies before they are filed, typed entries matter more here than on a form that stays inside one office.

Verify the edition before the first keystroke. The date on the form face should read not stated. If it does not, discard the file. Field numbering shifts between editions, and on a DD form the new layout reaches every receiving office in every service at once — there is no lag during which the old version is still normal somewhere.
For anything ambiguous in a specific field, the form's own instructions come first and not stated controls where the two differ.
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.
Revision follows directive changes, changed data requirements and amended notice language, unannounced. Verify not stated each time rather than trusting a saved copy — the cost of the check is seconds.
This page publishes a Defense document and explains its contents. It does not advise, does not rule on applicability, and determines nothing about how a completed form will be treated. Direct such questions to not stated, to the servicing personnel office, or to the office designated in not stated.
