DA Form 4660-1 handles one job: MILITARY AUXILIARY RADIO SYSTEM AUTHORIZATION TO OPERATE (WALLET CERTIFICATE). The official title is MILITARY AUXILIARY RADIO SYSTEM AUTHORIZATION TO OPERATE (WALLET 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.
CIO is the proponent, AR 25-6 the prescribing authority. Read the directive only if something about your situation departs from the standard case. Otherwise the form is filled by the individual it describes, or by the records clerk keeping the file, and reviewed through the printed signature blocks.
The formats are none published here, and the choice comes down to keyboard or pen. Fillable pdf for typing — live fields, tab order, saved entries. Printable pdf for handwriting — same page, no interactive objects, print it blank. Content is identical; only entry method differs.
Save the download and open it in a dedicated reader. That single step prevents the common failure: an in-browser viewer accepts your typing and discards it at tab close. Confirm with one field and one save cycle before committing the whole form.
Nothing is charged and no sign-up applies. Files are served as published, without changes to the page image.
Start at the top and get the header exactly right. Official spelling of the name, identification number, unit, date. Everything downstream finds the record through those entries; nothing else on the page has that consequence.
Move between fields with tab; the build-time order follows the page and misses nothing. Click check boxes and option buttons, and expect an exclusive group to release the old choice when you set a new one. The trap is field width. Single-line fields do not wrap, so an overlong entry displays complete on screen and prints cut at the margin — put it in remarks or on a continuation instead. Mark inapplicable fields rather than leaving them blank, since an empty box carries no information about whether the question was read.
Signature comes after every other entry — ink or an approved electronic means, and without it the document is a draft. Where reviewing, approving or witnessing signatures are called for, take them in printed block order, each dated on the day applied. Before release, one pass from the top. The defects worth hunting are always the same four: mandatory fields left empty, identification digits transposed, dates with day and month reversed, and stale data surviving in a copy reused in place of a blank form.
Read the Privacy Act statement at the point it appears. Authority, purpose, routine uses, mandatory or voluntary — four facts, and they govern what you are about to enter. A completed copy holds personal data and takes the handling rules that attach to it.
The prescribing directive names the destination; office custom does not. Depending on the case that means a specific office, the unit administrative channel, or the personal record. Keep a copy first, because the original does not come back. Retention runs on the applicable records schedule.
Related forms are found by series and number. DA series documents under the same proponent or the same prescribing directive are commonly required as a set, and any form named on the face of this one goes forward with it. Assemble continuations, covers and transmittals before submitting, not after the query comes back.
A stored file goes stale silently. The proponent revises, a new edition date is published, and your copy says nothing about it — so compare the printed date against the edition in force before typing into it again. Completed submissions on an earlier edition are not reopened.
These are reproductions of published Department of the Army documents, offered for download. The site is independent, connected to nothing official, and issues no forms of its own. Nothing here is legal advice and no statement is made about acceptance by any office. Questions about an entry, a requirement or eligibility go to CIO or your servicing administrative office.
