What is DA Form 4660? It is the Department of the Army form titled MILTARY AUXILIARY RADIO SYSTEM AUTHORIZATION TO OPERATE (CERTIFICATE), and it exists so that you can military auxiliary radio system station license (s&i usacc, ft huachuca, az 85613). That single line covers most of what people arrive looking for. The rest of this page fills in the details.
Is this the current version? The edition offered here is dated 04/01/2026, published with the status ACTIVE. That date is the version number of a military form; there is no other.
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.

What can I download here? The formats available are none published here. Each one reproduces the identical official layout. What separates them is the method of entry, nothing on the page itself.
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.
Do I need special software? Not for reading — a pdf opens in the browser you already have. For filling, install a full pdf reader rather than trusting the in-browser viewer, which sometimes displays fields it cannot save. Type into one field, save, reopen and confirm the text survived.
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.
How should you work through the entry fields? With the tab key. It follows the order the form was constructed in, which is usually the order the page reads, so nothing gets passed over. Do check boxes work the same way? They are clicked rather than tabbed into. In an exclusive group, a second click elsewhere clears your first choice, as intended.
Can a field hold a long answer? Not if it is sized for one line — there is no wrap, and the excess prints missing while remaining visible as you type. So where does the extra text belong? In the remarks area or a continuation sheet. Should you skip fields that are irrelevant to your case? No. Mark them accordingly, because an empty field reads as an oversight rather than an answer.
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.
What does the Privacy Act notice tell you? The legal authority behind the collection, what the information is for, the routine uses it may be put to, and whether disclosure is compulsory. When is the right moment to read it? Before completing the personal entries, at the point the statement appears. What follows from it? Your finished copy contains personal data, so store and send it the way your office handles that category.
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.
How do you find related forms? By series and number. Documents in the DA series sharing a proponent or a prescribing directive are commonly used together, and a form cited on the face of another usually goes forward with it. When should you gather them? Before submission — continuation sheets, cover sheets and transmittal documents belong in the package from the start.
What causes a form to be superseded? A revision issued by the proponent, after which the previous edition date no longer matches the one in force. How do you check a copy you saved? Read the edition date on the page and hold it against the current edition. Must earlier submissions be redone? They must not — a completed record executed on a prior edition is unaffected.
What exactly is this site? A place to download reproductions of published Department of the Army documents. Is it part of the Department of the Army? No — it is independent, issues no forms of its own, and has no authority over any of them. Can it tell you whether your completed form will be accepted? It cannot, and nothing written here is legal advice. Who answers the real questions? CIO or the administrative office servicing your unit, on any question of entry, requirement or eligibility.
