The exponential growth of small unmanned aircraft systems (sUAS) creates new risks for the United States with no current answers to appropriately respond in an effective manner. Technology trends are dramatically transforming legitimate applications of sUAS while simultaneously making them increasingly capable weapons in the hands of state actors, non-state actors, and criminals. The 2020 Nagorno-Karabakh War between Armenia and Azerbaijan is marked as a pre-eminent example of UAS use in conflict. The Army must protect and defend personnel, facilities, and assets in an environment where increasing numbers of sUAS will share the skies with Department of Defense (DoD) aircraft, operate in the airspace over DoD installations, and be employed by our Nation’s adversaries.
