If you believe you have suffered an injustice because of an error in your military records, you can apply for a change/upgrade. Please visit the Defense Finance and Accounting Service website.
Each branch of service has a drop-down option that gives you access to the application form(s) needed to make your request.
If you need assistance applying for a correction, visit the National Veterans Legal Service Program’s website and review their “Lawyers Serving Warriors” program. It is a pro-bono (free) service provided to veterans specifically needing assistance with the correction of military records, such as modifications and upgrades.
