Thanks, Steve, for the information.For the past year and a half I've been turning over any stone I could find: unfortunately there are few stones.The Signal Corps museum had no information.I had e-mailed the guy you mentioned for the 292nd JASCO and he never returned a reply. However contacting the guy for the 286th JASCO sounds like a good idea as they were also in Normandy and participated in that assault landing along with the 293rd. Jonathan Gawne's book "Spearheading D-Day" gave me the most direct information regarding my father as he has a chart in the book specifying which NSFCP was assigned to what regiment & battallion.On one of my fathers maps, he had scribbled "team #16" which according to this chart meant that he was assigned to the 115th regiment/29th div. calling in gunfire to the USS Thompson. So far, that's the only concrete thing I can find pertaining to his unit.
