I only know from my grandfather about the Russians, but he might recall seeing Germans one way or another. I'll call him right now.
EDIT - He said Germans usually hipshot, but that they liked to advance ironsighted, which, in his words:
"Probably did saved my life, because sometime the Germans went right past hiding spots because they no could for to see us hiding in there because they only look in sights."
Yes, he talks like that, I don't have a problem with grammar.
So basically, this issue needs to be put to rest.
