Werner von Blomberg
The OKW was the highest in the military command structure. It was responsible for the co-ordinated effort of the three military arms. It was headed by Wilhelm Keitel after he took over from war minister Werner von Blomberg in 1938. Since the head of the Luftwaffe, Göring, was also a cabinet minister, any Luftwaffe operational orders would come from Hitler to him, who would pass them on to Luftwaffe leaders, bypassing the OKW.
