Eagles Overhead provides a critical history of US Air Force Forward Air Controllers and examines their role, status, and performance in the Air Force's history. It begins by examining the US's initial adoption of air power, and American participation in aerial combat during World War I and traces the FACs' contributions to every US Air Force air campaign from the Marne in 1918 to Mosul in 2017. However, since 2001 FACs' contributions have been sporadic. Eagles Overhead asks why, despite the critical importance of FACs, have they not been heavily used on US battlefields since 2001? It examines the Air Force FAC's theoretical, doctrinal, institutional, and historical frameworks in the first nine chapters to assess if the nature of air warfare has changed so significantly that the concept and utility of the FAC has been left behind. Or, has the FAC been neglected since 2001 because the Air Force dislikes the capability as it clouds the service's doctrinal preferences? From these examinations, Eagles Overhead draws conclusions about the potential future of Air Force FACs.
