I know. It is my understanding that the regular German army was not involved in as many of the atrocities. The worst stuff was usually done by the SS and such.
I'm pretty sure most Germans just served because their country demanded it of them.
From what I have read, pretty true, at least in Western Europe, the Mediterranean and North Africa. Russia was a different story. There the German Army was, in some cases, almost as brutal to the local populations as the SS. One example is the City of Kharkov. The Germans would not feed anyone not working directly for the army. Thousands of Kharkov citizens starves to death as a result of that policy. This also happened in a lot of cities occupied by the German Army in the Soviet Union.
