Actually Lipton began with an M1 Garand which he lost on the DDay jump. Over the night he picked up a German MP40 as seen in Band of Brothers. The next morning he picked up an M1 Carbine with folding para stock from a dead paratrooper. He had that weapon up until Bostogne where he had an M1 Garand. Thats what I think happened.
