There was no mention of the 82nd or 101st in discharge papers, but you may be correct in thinking he may have been assigned to different groups as needed. Sister and I cannot remember shoulder patch on his uniform.
I, too, googled the 460 and got the impression he was with the 82nd because of the places he served.He supervised 22 men laying radio communications and did radio operation and maintance. He had 43 jumps on his record, but I don't know how many were in training or under battle conditions.
Another soldier who served in same place at same time said the 82nd and 101st were constantly being replenished because of all the men who were lost. Sad.
