DA Form 3126 belongs to the DA series of Department of the Army publications. Its official title is APPLICATION AND CONTRACT FOR ESTABLISHMENT OF A JUNIOR RESERVE OFFICERS` TRAINING CORPS UNIT, and its stated purpose is application and contract for establishment of a junior reserve officers` training corps unit (s&i, hqda, attn: tapc-opp-p, 200 stovall st., alexandria, va 22332-0418). Edition in force: 04/01/2023. Publication status: ACTIVE. Length is 4 page(s), with roughly 200 fields available for entry.
Responsibility for content and revision lies with G-1. The prescribing directive is AR 145-2, 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. This edition has been superseded by a newer one. It is kept accessible for reference and for records already completed under it.
Available formats: PDF. Each is a rendering of the same official layout; the content is identical across them and only the means of completion differs. The pdf is the reference copy. Fillable pdf carries interactive form fields; a printable pdf is the same page image without them, intended for pen entry 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.
All formats are free to download and no registration is involved. The files are the published documents, distributed unmodified.

Entry proceeds block by block in the order printed on the page. Identifying particulars occupy the head of the form: name, identification number, unit or organisation, and date of preparation. These fields govern how the record is later retrieved from the file, so they are completed before any substantive block.
Interactive fields are filled by typing into them. Movement between fields is by tab, following the order established when the form was constructed, which usually tracks the page layout. Check boxes and radio groups are set by clicking, and exclusive groups permit one selection at a time. A one-line field has no wrap: text beyond its width prints truncated even when the screen shows it. Overlong content is placed in remarks or on a continuation, not forced into the field.
The signature block is the final entry, made by hand or by an authorised electronic method, and without it the document remains a draft. Countersignatures — review, approval, witness — are added in the sequence printed, dated at the moment of signing and not at preparation. Empty mandatory fields lead the list of defects; an inapplicable field is annotated as such, not passed over. Behind it come digit transposition in identification numbers, day-month inversion in dates, and residual entries surviving from a reused copy in place of a blank form.
A Privacy Act statement appears on the form where personal information is collected. It sets out the authority for collection, the purpose, the routine uses, and whether disclosure is mandatory or voluntary. The statement is read before entry, not after. Completed copies carry personal data and are handled and stored under the safeguards applicable to that data.
Disposition of the completed document follows the prescribing authority — delivery to the office it names, transmission through the unit administrative channel, or placement in the individual's record, according to circumstance. The preparer keeps a copy. Retention is governed by the applicable records schedule, not by office custom.
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.
Editions are replaced when the proponent revises the content. The edition date printed on the form is the means of telling one version from another, and the date on a downloaded copy is checked against the edition in force before use. Records already executed on a prior edition are not reworked on that account.
The files here are reproductions of published Department of the Army documents, provided for download. This site is not part of the Department of the Army and issues no forms of its own. Nothing on this page is legal advice, and no representation is made as to acceptance of a document by any office. Where an entry, a requirement, or a question of eligibility is in doubt, the proponent or the servicing administrative office answers it.
