My father was in the 846th EAB:
846th Engineer Aviation Battalion (EAB)
'Landing in Normandy on July 16th, this unit had completed A-13 by July 26th, a fighter-bomber base with two PSP runways. The 846th has completed three ALGs, two S and Es, one fighter-bomber strip, and has rehabilitated 20 airfields. Operations carried them from Normandy, through France, Belgium, Holland, and into Germany where V-E Day found them working on Bremen Airfield.'
He was issued an M1 carbine; I have seen a photo of him with it.
And, I managed to find the photo.
He helped build landing strips after D-day, bringing supplies in, and carrying the wounded back to the hospital.
He had worked for a company that made asphalt road paving equipment (and other heavy machinery) so because of his valuable skills, he was not in combat, although snipers tried to get him more than once, as he was sent into an area as soon as it was 'secure', to provide a landing strip.
Often, German snipers were still in these areas.
I heard very very few WWII stories from him.
Like many vets, he didn't like to talk about the war, at all.
Here he is, running a ditching machine.
Sorry, I messed up and added the same pic twice; I can't figure out how to remove the duplicate.
