Reichsgau Wartheland
There was also a German storm brigade known as the "Volksdeutscher Selbstschutz" formed by the German minority in Poland. Many of its members were trained in the Third Reich. As soon as the war started, the "Selbstschutz" engaged in widespread massacres of Poles and Jews in West Prussia, Upper Silesia and Reichsgau Wartheland, together with the "Einsatzgruppen".
