A Default — Military Affidavit is a legally binding statement of fact, used to verify military service and to provide proof of military status. It is typically used in the event of a dispute or disagreement between parties regarding a veteran's eligibility for certain benefits, such as those related to disability or death. Types of Default — Military Affidavit include the Standard Form 180 (SF-180), the Alternate Form 180 (AF-180), the Enlisted Record Brief (ERA), and the Officer Record Brief (ORB). The SF-180 is the most commonly used form, and it requires the veteran or their representative to provide a detailed account of their service history. The AF-180 is used when a veteran's records are incomplete or otherwise unavailable. The ERA and ORB are used to provide an overview of a veteran's service history.
