Download the form
DA Form 4660 handles one job: military auxiliary radio system station license (s&i usacc, ft huachuca, az 85613). The official title is MILTARY AUXILIARY RADIO SYSTEM AUTHORIZATION TO OPERATE (CERTIFICATE). Download it below, fill it in, sign it, send it where your directive says. The edition on this page is 04/01/2026, status ACTIVE, running unknown page(s) with about unknown fields to complete.
Authority sits in two places. CIO owns the form, AR 25-6 says when it is raised and where it goes. Routine cases need neither read in full — the page itself carries the sequence. The entries are completed by their subject or by unit administrative staff working from what that person supplies.
none published here are available and the decision takes one second. Type your entries: fillable pdf. Write them: printable pdf. The published layout is common to both, so the format governs your method and nothing more.
A standalone reader is the safe choice for fillable work. Browser viewers vary in whether entered data survives the session, and there is no warning when it does not; a one-field save test settles it in seconds.
Free, unregistered, unmodified. What arrives is what the publisher released.
Header first, always. Name as your official records spell it, identification number, unit, date of preparation — these four index the finished record, and an error in them hides the document from anyone searching for it later. The substantive blocks can wait thirty seconds.
Tab through the fields rather than clicking. The tab order was fixed when the form was built and generally follows the page, which catches boxes a mouse skips past. Check boxes and option buttons take a click, and an exclusive group clears the previous selection when you make a new one. Single-line fields do not wrap — text past the field width prints truncated while still showing in full on screen, which is why the loss is discovered after printing. Overflow goes to remarks or a continuation sheet. A field that does not apply gets the mark meaning none; blank space reads as an omission.
The signature closes the form and nothing precedes it. Draft status holds until it is applied, by hand or by an accepted electronic method. Countersignatures go in printed order, each dated at signing. Then one final read from the top, looking for the four recurring defects: empty mandatory fields, swapped digits in identification numbers, day-month inversion in dates, and residue from a reused file that goes forward as though intended.
The Privacy Act statement is read before the personal entries, not after. It gives the collection authority, the purpose, the routine uses and whether disclosure is mandatory or voluntary. Once filled, your copy is a personal record and gets stored and transmitted accordingly.
Send it where the directive says: the office it names, the unit administrative channel, or the individual's file. Take your copy before submission. How long the record is held comes from the schedule for the series, not from the office holding it.
Companion documents come from the same series and number scheme. Within the DA series, a shared proponent or a shared directive usually means shared use, and a form cited on the face of another accompanies it. Gather the whole package first — continuation sheets, cover sheets, transmittals.
Check the edition date before reusing a saved copy. Revisions come from the proponent without notice to you, and the printed date is the only version marker on the page. Already-submitted records under a superseded edition stand as filed; the change does not run backwards.
What is distributed here are reproductions of published Department of the Army documents. Independent site, no official standing, no forms of its own. Nothing on the page constitutes legal advice, and acceptance by any office is outside what can be stated. Put questions about entries, requirements or eligibility to CIO or your servicing administrative office.
