Watching WW2 films like 'The Pacific' and 'Band of Brothers', I got an idea of what kinds of souvenirs American soldiers scavenged off of enemy soldiers - e.g Flags, Japanese swords, and German Luger pistols. That gave me the thought of what kinds of things the axis soldiers found valuable. I'd guess they'd be similar things but came here to see if that was the case or not. Any ideas?
The Germans particularly liked M1 carbines and rations from US forces. More can always be said on the matter, especially from the Japanese side of things, so if anyone can contribute on that end, that would be greatly appreciated. As well as just further posts that can provide more answers to the question, as we'll never turn good ones down. For the meantime, OP, you may be interested in u/the_howling_cow's answer to just this question.
