My Dad, Ernest Orsi, remembers his name and thinks he was in one of the service groups that assists the tank group. It could be medical or mechanical, etc. But other than that, Eugene's group was not close to my Dad's specifically.
I e-mailed the National Archives for all the details of my father's military life, beginning to end. I gave them as many details as I knew. Within two weeks, I received a letter stating that they had found the records; 105 pages! @ .50 per page. I have them now and have copied and given them to my Dad. He was pretty surprised and impressed that they still had these records (there was a fire in 1973 that destroyed a lot of military service records) and that they would let us have them. They were declassified some time ago. There are pages of their early training, after action reports (battles), and commendations; Purple Heart, Oak Leaf Clusters, and who received them and what they did to merit them. Just go to www.nara.gov and find where to e-mail for information.
