DA Form 4660 belongs to the DA series of Department of the Army publications. Its official title is MILTARY AUXILIARY RADIO SYSTEM AUTHORIZATION TO OPERATE (CERTIFICATE), and its stated purpose is military auxiliary radio system station license (s&i usacc, ft huachuca, az 85613). Edition in force: 04/01/2026. Publication status: ACTIVE. Length is unknown page(s), with roughly unknown fields available for entry.
Responsibility for content and revision lies with CIO. The prescribing directive is AR 25-6, which sets both the trigger for use and the disposition of the completed document. Entry is made by the named party or by the records clerk holding the file, with review and signature applied in the prescribed order.
Distributed formats: none published here. The layout is common to all of them; what varies is the method of entry. The pdf is the reference version. In the fillable pdf the entry areas are live objects that accept typing; in the printable version the same areas are inert and are filled by hand after printing.
A pdf opens in any current browser or in a dedicated reader. Fillable behaviour is more reliable in a full reader than in a browser viewer, where some field types render but do not save.
Every format is available at no charge and without sign-up. Files are distributed exactly as published, with no changes to the page.
The blocks are worked through in the order they appear on the sheet. At the head sit the identifying entries: name, identification number, unit, date. Because the filed record is indexed on these, they precede everything substantive.
Typed entry is made straight into the interactive fields. The tab key moves through them in the order set at build time, generally matching the reading order of the page. Boxes and buttons respond to a click; in an exclusive group, one selection cancels the others. Single-line fields do not wrap, and anything longer than the field width prints cut off although it may still display in full on screen. Extended text goes to remarks or a continuation sheet rather than into a narrow box.
The signature block is completed last and by hand or by an accepted electronic means. An unsigned form is a draft. Where a second signature is called for — reviewing official, approving authority, witness — each is applied in the order the blocks appear and dated as of application, not as of preparation. Blank mandatory fields are the most frequent defect; a nil entry is marked as such rather than left empty. Other recurring faults: transposed digits in identification numbers, dates in the wrong order of day and month, and stale copies retaining prior data because a working file was reused instead of a fresh blank form.
Forms that collect personal information bear a Privacy Act statement covering authority, purpose, routine uses, and whether the disclosure is required or optional. Reading it precedes completion. Once filled, the document contains personal data and is subject to the handling and storage rules that attach to such records.
The completed form is routed as the governing authority prescribes: to the office named in the directive, through the unit administrative channel, or into the individual's file, depending on the case. A copy is retained by the preparer. Filing and retention follow the records schedule applicable to the series rather than local practice.
Related forms are found by series and number. Documents in the DA series sharing a proponent or a prescribing directive commonly travel together, and a form referenced within the body of another is usually filed with it. Continuation sheets, cover sheets, and transmittal documents belong to this group and are collected before submission rather than after.
Revision by the proponent supersedes an edition. Version is read from the edition date printed on the form itself, and a stored copy is compared against the current edition before it is used again. Documents already executed under an earlier edition are not redone because of the change.
What is offered here are copies of published Department of the Army documents, made available for download. The site is independent of the Department of the Army and publishes no forms of its own. The material is informational and not legal advice, and no statement is made about whether any office will accept a given document. Questions of entry, requirement, or eligibility go to the proponent or the servicing administrative office.
