Close air support from the Luftwaffe also played an important role in this early success. It contained the Red Air Force, through air superiority operations, and provided interdiction through attacks on airfields and Soviet defence lines. At times, the German air arm acted as a spearhead rather than a support force, ranging on ahead of the tanks and infantry to disrupt and destroy defensive positions. As many as 100 German aircraft were concentrated on a single Soviet division in the path of the spearhead during this phase. General Kazakov, the Bryansk Front's chief of staff, noted the strength and effectiveness of the Axis aviation. Within 26 days, the Soviets lost 783 aircraft from the 2nd, 4th, 5th and 8th Air Armies, compared to a German total of 175.
