I just found a photo of my maternal grandfather, Paul Clarence Westad.
The patch on his arm says he was an Army technician, 5th class — that meant he served in a non-combat role, but had specialized skills. He was a farm boy straight out of northern Minnesota, and I think his skill was being able to drive a tractor. From the little he said about his service, he was driving a bulldozer and building airfields on remote Pacific islands, but he didn’t talk much at all about what he did. He would tell stories about the giant lizards living in the rafters of his hut, and he had a secret stash of photos he smuggled out at the end of the war that showed burned and chopped up Japanese corpses, so I think part of his duties involved burial details.
He came out of the war with incipient alcoholism and possibly a bit of PTSD. He worked for the Washington State highway department driving a bulldozer, naturally enough, until the alcoholism left him a wreck. I have great memories of him when I was a child that turned into horror stories when I was an adult. I don’t know if I can blame the war, but maybe.
