On January 27, 1943, Gable reported to Biggs Army Airfield, Texas to train with and accompany the 351st Bomb Group to England as head of a six-man motion picture unit. In addition to McIntyre, he recruited the screenwriter John Lee Mahin, camera operators Sgts. Mario Toti and Robert Boles, and the sound man Lt. Howard Voss, to complete his crew. Gable was promoted to captain while he was with the 351st Bomb Group at Pueblo Army Air Base, Colorado, a rank commensurate with his position as a unit commander. (Prior to this, he and McIntyre were both first lieutenants.)
