Welcome Kelly!! I would think that most vets of GD would be quite old by now, but you will be very interested in our sister site www.feldgrau.com
, because under the HEER section you will find the memoirs of Rudi Salvermoser, a GD vet. Rudi had an interesting war to say the least, having guarded the perimeter at Hitler's Wolf's Lair etc. Good luck with your research and let us know if we are able to help!! Best wishes.
