The U.S. Army didn't loot Germany after the war was over, but while it was still on they had the authority to seize weapons and about anything else the enemy could use. When an allied unit entered a German town, they posted orders for everyone to bring out guns, signal equipment, etc. The guns were laid out on the streets, and GI's allowed to take what they wanted, then tanks were run over them. The GI's didn't care if it was a G.43 some SS man left in the house or a 200 year old flintlock shotgun, it was destroyed.
Of course, most GI's didn't want to admit that they got some German hunter's or target shooter's pride and joy, so they told the folks at home that they "took it off" a German general. One man told me that he took his Walther PPK "offn old Adolf hisself when we captured him." I said that I thought Hitler committed suicide in Berlin. "Well," the vet said, "That was later see, we turned him over to the lootenant and that goldbrick SOB let him get away."
Yep, the "greatest generation" may have been great heroes, but they were also great liars.
