Close air support
In June 1939 during the General Staff Ride, Jeschonnek stated unequivocally that upon the declaration of hostilities the Luftwaffe should not direct all its power to destroying the enemy air force(s). Close air support operations for the army were most important. His remarks were a repudiation of aerial doctrine established by his mentor, Wever and Helmuth Wilberg in the 1920s and 1930s, "Conduct of the Air War" to which Jeschonnek had contributed.
