Kurt von Schleicher
Buchrucker's Black Reichswehr took its orders from a secret group in the German Army known as "Sondergruppe R" comprising Kurt von Schleicher, Eugen Ott, Fedor von Bock and Kurt von Hammerstein-Equord. The Black Reichswehr became infamous for its practice of murdering Germans suspected of working as informers for the Allied Control Commission.
