I often hear and see mention that the Germany army was seperate from the SS and didn't know about the atrocities committed by Nazis in WW2 but it is nearly always called out as a load of crap. However, neither side seems to ever provide evidence outside of conjecture. Is there anything concrete on this? Is there anyone here with some background on the subject?
There is a lot of material in u/commiespaceinvader's back catalogue on this question, perhaps particularly this answer on the tricky question of scale, but it all boils down to no, it's in no way true and there's plenty of evidence of Wehrmacht participation in and complicity with war crimes and other atrocities. I always found this thread (with further detail from u/Georgy_K_Zhukov) on the origins of the Clean Wehrmacht myth to be particularly interesting.
