Much more can be written, but there are several articles in the FAQ section "German Military" that seem to apply. Opinions may differ, but the ones I see:

• "Is the use of 'Nazi' as a general demonym for referring to members of the German armed forces during World War II correct?" by /u/Astrogator. This includes a discussion of what "is a Nazi" can even mean.
• "How invested in Nazi ideology was the average German soldier?" by /u/TheCzarOfPie.
• "Just how much of the Wehrmacht was dirty?" by /u/commiespaceinvader
• for more on the "clean Werhmacht" / "clean Rommel" myths, you could read the entire Erwin Rommel subsection (Georgy_K_Zhukov, Aleksx000, commiespaceinvader)

This is not to discourage discussion. More questions, data and debate are welcome.
