Tibbets had flown 25 combat missions against targets in France when the 97th Bomb Group was transferred to North Africa as part of Major General Jimmy Doolittle's Twelfth Air Force. For Tibbets, the war in North Africa introduced him to the realities of aerial warfare. He said that he saw the real effects of bombing civilians and the trauma of losing his brothers in arms. In January 1943, Tibbets, who had now flown 43 combat missions, was assigned as the assistant for bomber operations to Colonel Lauris Norstad, Assistant Chief of Staff of Operations (A-3) of the Twelfth Air Force. Tibbets had recently been given a battlefield promotion to colonel, but did not receive it, as such promotions had to be confirmed by a panel of officers. He was told that Norstad had vetoed the promotion, saying "there's only going to be one colonel in operations."
