What happened if a soldier was found with a Star of David around his neck?
/u/commiespaceinvader has previously answered In WWII Europe, if a Jewish Allied soldier was captured by the Nazis, were they treated like other POWs, or were they treated like Jews from the general population and sent to extermination camps? but this is a very popular question and someone else might have more to say on it specifically about POWs from the USA
