Is there any history of US arms being used by the Wehrmacht other than during the Battle of the Bulge? They did use captured arms from many European countries.

B-17F-27-BO "Wulf Hound"
There's a whole story about this particular craft, how it was shot up and forced to land, then repaired and flown back to Germany for testing and evaluation. Then later in the war it was used in clandestine operations and its history gets sketchy and hard to track. The Germans got up to lots of shenanigans with it, then it pretty much vanished. There's speculation it was used at the end of the war to ferry high ranking officials out of the country right over the heads of the advancing allies.

An American built M4A3 (76) Sherman medium tank, captured and pressed into service by the German army. German markings and the words Beute Panzer (captured tank) were painted on the tank to avoid friendly fire. The tank was knocked out by a US M36 Jackson tank destroyer. A dead crew member lies on the front of the tank, probably hit by machine gun fire while attempting to bail out of the stricken tank. Aschaffenburg, Germany. 1945

This one is particularly interesting, because it's more than one tank, and a Jeep in the foreground to boot.
