Major Kramlinger examines the theoretical, historical, operational, and technological aspects of Sustained Coercive Air Presence (SCAP) and illustrates how air operations over Iraq and Bosnia demonstrated the problems associated with long-term air presence and suggest the need for doctrine that adapts combat airpower to the SCAP mission. He focuses on the determination of the mechanisms, strengths, and limitations of how combat airpower can persuade determined belligerents to stop fighting and then maintain a secure environment to facilitate the continuing diplomatic process.
