See my works der Einsatzgruppe and the Destruction of European Jewry and Babi Yar a Jewish Catastrophe. There were many cross overs between ranks of Einsatz, Waffen SS and Wehrmacht. Each competed in the slaughter of the Jews, other Nationals and local partisan groups. There is a distinction between Einsatz, expressly detailed for the mass murder of Jews, The Holocaust, The Final Solution, and Reich involvement in WWII.
