Every entry in the Defense records system exists because some decision needed a documented basis, and DD Form 2641 is one of those instruments: Trafficability Test Data, created to Trafficability Test Data. 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.
The practical effect of Department-level issue is interoperability. not stated establishes the requirement across the Defense enterprise; not stated keeps the document current for all of it. No service maintains its own variant, which means a completed record travels between components — service to agency, agency to joint command — and arrives in a format the receiving office already knows how to read.
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.
The sequence printed on the form is the sequence in which a reviewer will read it, and the two should agree. Header data frames every entry below it; the substantive fields depend on that frame; the certification stands at the end because its whole function is to vouch for what came before. Entries made out of sequence commonly contradict entries made earlier.
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.
For an ambiguous field, read the form's own instruction, then not stated, which controls.

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.
Fillable and printable are not two presentations of one file but two different objects. One holds your entries as structured data within the document; the other is a static picture meant to meet a pen. Since a DD form frequently moves outside the organization that created it, the durability of the entry matters more here than on a record that stays in one drawer. Typed text reproduces indefinitely; handwriting degrades at every copy.
Route the executed form as not stated or local guidance directs, and retain a duplicate first. Cross-component routing is ordinary for DD forms, which is precisely why a personal copy earns its keep: the receiving office may belong to an organization you have no standing to query about a missing document.
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.
Procedures that touch both Department and service processes will cite forms from both sequences, and the coincidence of numbers between them is exactly that — coincidence. An Army proponent maintains the DA series for the Army; not stated or another Department office maintains the DD series for the whole Department. Two independent registries, two independent numbering runs, no correspondence at any value.
Editions change for reasons that originate above the form itself. The prescribing directive is reissued and the form follows; the information the Department needs to collect changes and the fields change with it; the statutory notice language is amended and every form carrying that notice is republished. None of these events announces itself to the person who downloaded a copy last year, which is why confirming not stated at the moment of download is the only reliable check available to you.
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.
