After reading about xcopterdoc's loss and not wanting to take that thread off topic I thought I would start a new one for the veterans out there.
Should you want to be buried in one of the military cemeteries around the country, the way it worked was once the veteran passes, then you can go down to the cemetery with the DD214 and start the process. Of course that may mean a loved one trying to do this process and if they have never been in the military the probably have no idea what a DD214 is or where the veteran kept their copies.
This has changed in recent years where you can go down to the cemetery with your DD214 and get the verification done ahead of time.
I just thought I would mention it in the event that it might help someone out there.
