Only a few states are known to have used unmanned armed drones but an increasing number is seeking to acquire this technology. Although technological progresses have spurred the development of increasingly autonomous weapons, the precise delineation between an armed drone and a fully autonomous weapon system (sometimes termed a 'killer robot') is unclear.
Armed drones are widely seen as the beginning of a trend that will lead to the use of systems capable of targeting and killing one or more persons with complete autonomy from human intervention. On the other hand, non-armed drones are used to assist humanitarian action in the field and unarmed surveillance drones are used for civilian rescue and law enforcement. At the same time, in the same countries, both armed drones and increasingly automated drones are being acquired by armies and potentially by armed non-state actors for use in combat.
