Air power has traditionally been wielded solely by large, well-financed government organisations composed of highly skilled people but no more. With the rise of low-cost, commercial off-the-shelf drones, small armed non-state actor groups can today also employ air power. This change was initially convincingly demonstrated with the use of such drones offensively in Iraq by the Islamic State of Iraq and Syria (ISIS) during 2014–2017. This chapter initially discusses the technological developments that made this revolution possible and the early employment of drones by ISIS, particularly during the battle for control of Mosul. The second section considers the potential implications of these developments for future defence force operations including non-state actors fielding air reconnaissance capabilities in urban battlefields, that non-state actor drones may be armed, and that drone defence will be required on the future battlefield. The conclusion reflects on changes needed to generic air power theory. Air superiority can no longer be assumed in wars against non-state actors, consumer technology can now provide useful air power and that such drones have shifted air power away from governments and to the people. Consumer drones have privatised air power.
