An issue that comes up, unfortunately way too frequently, is a veteran's records were destroyed in 1973 at the St. Louis fire at the National Personnel Records Center. For information on how to contact the National Personnel Records Center see my link under my Helpful Resources and National Personnel Records Center, St. Louis at the bottom of this page http://www.attorneyforveterans.com/lawyer-attorney-1324329.html
VA Regional Offices often deny a claim based upon "They (VA) could not obtain the records, and they were destroyed in a Fire at the NPRC." Then the next 7 states that it is the veteran's responsibility to obtain the records. One of the requirements to obtain a VA disability rating is to provide evidence that a disease, injury, or event occurred in service creating a disability that continues to this day.
