What is DA Form 4660-1? It is the Department of the Army form titled MILITARY AUXILIARY RADIO SYSTEM AUTHORIZATION TO OPERATE (WALLET CERTIFICATE), and it exists so that you can MILITARY AUXILIARY RADIO SYSTEM AUTHORIZATION TO OPERATE (WALLET CERTIFICATE). That single line covers most of what people arrive looking for. The rest of this page fills in the details.
Which edition is on this page? The one dated 04/01/2026, status ACTIVE. On army forms the edition date is the version, printed on the page itself so any copy can be checked.
Who fills it out, and how long does it take? The individual named in the entries fills it, or a records clerk fills it on that person's behalf. Length is unknown page(s) with about unknown entry fields, which is the honest measure of the work involved. Who owns the form and when it is raised comes from CIO and AR 25-6 respectively.

Which formats can I download? These: none published here. All of them carry the same published page — the difference is not what the form says but how you get words onto it.
What is the difference between fillable and printable? A fillable pdf has live fields that accept typing and can be saved with your entries in place. A printable pdf is the same blank page with no live fields, meant to come out of a printer and be completed with a pen. Both print identically once filled.
Which application should I use? Reading takes nothing beyond a browser. Filling takes a proper pdf reader, since browser viewers vary in whether they retain what you type — verify with a single field and a save before you fill the whole form.
Is it free? Yes, entirely. No registration stands between you and the file, and what arrives is exactly what the publisher released.
Which entries come before the rest? The identifying ones at the head of the page: name, identification number, unit, date of preparation. Does it matter that they come first? Yes — everything downstream retrieves the record by those values, so they are worth getting right before you touch the substantive blocks.
What is the fastest way to fill the body? Tab from field to field. The order was set at build time and normally matches how the page reads, which is why tabbing catches boxes that clicking past would leave empty. And the boxes and buttons? Those take a click. Where only one option in a set can apply, choosing one deselects the other.
Why does my text vanish when I print? Because one-line fields have no wrap, and anything past the field width is truncated on paper even though the screen shows all of it. Where should the overflow go? Into remarks, or onto a continuation. What about entries that do not apply? Enter the mark meaning "none". Blank space is ambiguous; a reviewer cannot tell an omission from a considered nil.
Is a signature really the last step? Yes, and without it you have a draft, not a form. Who else signs? Whoever the form calls for — reviewer, approver, witness — in printed block order, each dated as of the day they sign. Which errors cause the most returns? Blank mandatory fields lead, followed by identification numbers with two digits swapped, dates written day-for-month, and leftover data in a reused file that goes forward as though it were meant.
Why does the form carry a Privacy Act statement? Because personal information is being collected, and the statement declares the authority, the purpose, who else routinely sees the data, and whether answering is required or optional. Is it worth reading? Read it before you fill the fields it governs, not after. Does it change how you keep the file? It should — a filled copy is a personal record and gets the handling such records receive.
Where do you send it? To the destination the prescribing directive names, which may be a specific office, the unit administrative channel, or the individual's file. Is a copy worth keeping? Always, and taken before submission. How long does the receiving office keep it? For the period the records schedule for the series prescribes, regardless of local custom.
Which other forms travel with this one? Those found by series and number: DA series documents sharing a proponent or a governing directive are frequently needed in combination, and a form referenced on the face of another generally accompanies it. Do you assemble them before or after sending? Before. Continuation sheets, cover sheets and transmittals are part of the same package.
When is an edition replaced? When the proponent revises the form and publishes a new edition date. What should you do with a copy kept on your own machine? Check its date against the edition in force before reusing it. Does the change reach backwards? It does not; work already completed on an earlier edition remains valid as filed.
Is this an official Department of the Army site? No. It is an independent site distributing reproductions of published Department of the Army documents for download, with no authority to issue forms. Does it guarantee acceptance of anything you submit? It does not, and nothing on the page is legal advice. Who should you ask instead? CIO or your servicing administrative office, whenever an entry, a requirement or your eligibility is in doubt.
