Otto Skorzeny
It was said that even Himmler feared him, as Kaltenbrunner was an intimidating figure with his height, facial scars, and volatile temper. Kaltenbrunner was also a longtime friend of Otto Skorzeny and recommended him for many secret missions, allowing Skorzeny to become one of Hitler's favorite agents. Kaltenbrunner was also responsible for heading Operation Long Jump, a plan to assassinate Stalin, Churchill, and Roosevelt in Tehran.
