Request to have military records corrected are handled through your branch of service. Each service branch has a Board for Correction of Military Records. All requests to correct an error to one's military record must be filed within three years of discovery of the error along with a DD Form 149 and evidence, such as signed statements from you and other witnesses or copies of records that support your case. Applying for correction is a simple process; however, it is recommended that you seek the assistance of a Veteran Service Officer or contact the state Office of Veterans Affairs.  

DD form 149

You must make your application for discharge upgrade within 15 years of discharge. If your discharge is older than 15 years, you must apply for a change to your military records using the process detailed above (Correction of Military Records). You will need to complete the DD form 293 (Application for the Review of Discharge or Dismissal from the Armed Forces).
