As unmanned aerial vehicle (UAV) technology becomes ever cheaper and more accessible, the threat of armed and GPS-guided drones is becoming a serious problem for U.S. forces in theater.

Experts from MEI's Defense & Security Program weigh in with their thoughts on how the U.S. should respond to this emerging threat, as part of the new Defense Rapid Reaction series.
