Drone Warfare, by John Kaag and Sarah Kreps

Drones are unmanned aerial vehicles (UAVs) that can carry a payload for the purpose of reconnaissance and surveillance; and those that are armed with missiles and bombs carry a payload for combat use. So, in drone warfare a human being, that is, a pilot flying an aircraft, is unnecessary and his life is not put in danger over the enemy territory. In military technology, drones represent precision weaponry and the rise of robotics. Drones were not armed at all till the 1990s. They were only used as unmanned sensor aircrafts with predators operating in Bosnia, Kosovo and the no-fly zone in Iraq.
