DA Form 71, Oath of Office - Military Personnel is a form that is used to create a record of the date of acceptance of appointment as an officer in the Army of the United States. The form must be completed by all newly-appointed officers. Failure to file will make the appointment invalid.
The most recent version of the form - sometimes incorrectly referred to as the DD Form 71 - was released by the Department of the Army (DA) in July 1999 with all previous editions being obsolete.
The form contains an oath of office which must be filled in, subscribed, attested and returned to the agency from which it was received. In case of non-acceptance, the form must be mailed back to that agency.
The Oath of Office form is unclassified and approved for public release with unlimited distribution. An up-to-date fillable DA Form 71 is available for download and online filing down below or can be found through the Army Publishing Directorate website.
