How do you identify that isn't included? Ignore if intrusive. There may be a way for a custom medallion to be added to a VA provided headstone. I've seen a few in civilian but not VA cemeteries.

Ignore if intrusive. Let me revise, it is intrusive, but I'm interested.

An even less useful tidbit on the dog tag is your blood type. Over the years I have asked lab heads/techs, trauma surgeons if they would under any circumstances use that information for a clinical decision. Greeted with a universal snort.

During mass casualty exercises I would be assigned to the dirty side of Triage to assist with decon and assigning of priority. Sometimes I would get the 'expected' tent. Kind of like acute hospice. Make the psychiatrist useful, but out of the way.
