In 1941, Hitler gave the Oberkommando des Heeres the control of the war in the Soviet Union and told them they did not have to abide by the rules of war. The Oberkommando der Luftwaffe, the Oberkommando der Kriegsmarine and the Oberkommando des Heeres were subordinate to the Oberkommando der Wehrmacht which was ultimately responsible to Hitler for the operational conduct of the three armed branches of the German forces.
