Hitler ordered the SD and the Security Police to suppress the threat of native resistance behind the Wehrmacht's fighting front. Heydrich met with General Eduard Wagner representing Wilhelm Keitel, who agreed to the activation, commitment, command, and jurisdiction of Security Police and SD units in the Wehrmachts table of operations and equipment (TOE); in the rear operational areas, the "Einsatzgruppen" were to function in administrative sub-ordination to the field armies in order to effect the tasks assigned them by Heydrich. Their principal task (during the war), according to SS General Erich von dem Bach, at the Nuremberg Trials: "was the annihilation of the Jews, Gypsies, and Soviet political commissars". They were a key component in the implementation of the "Final Solution of the Jewish question" (German: "Die Endlösung der Judenfrage") in the conquered territories. These killing units should be viewed in conjunction with the Holocaust.
