He was 25th Infantry infantry, the Tropical Lightning Division in Guadalcana, and the shoulder patch
is the Toro Leaf with a lightning bolt down the center but he was, I think, with a divisional intelligent unit.
Must have been reassigned after his dismissal from hospital. Thanks, @Lewkat
He never talked about his military service except to say he was with the 25th Infantry, an intelligence unit, was wounded on Guadalcanal,
spent some timne in a hospital in Northern Australia, then transferred stateside to a hospital. He is my uncle now deceased. We both served
in the 25th Infantry. I didn't know or remember the above patch.
