Laws of War & Ethics
See also: Targeted killingThe international laws of war (such as the Geneva Conventions) govern the conduct of participants in war (and also define combatants). These laws place a burden upon participants to limit civilian deaths and injuries through proper identification of targets and distinction between combatants and non-combatants. The use of completely autonomous weapon systems is problematic, however, because of the difficulty in assigning accountability to a person. Therefore, current designs still incorporate an element of human control (a "man in the loop") – meaning that a ground controller must authorize weapons release.
Concerns also include the human controller's role, because if he is a civilian and not a member of the military (which is quite possible with developmental and highly sophisticated weapons systems) he would be considered a combatant under international law which carries a distinct set of responsibilities and consequences. It is for this reason that the "man in the loop" should ideally be a member of the military that understands and accepts his role as combatant. However, in the United States in 2011/2012 the process for selecting targets outside of warzones was altered so that power was concentrated within a group of people in the White House.
Controllers can also experience psychological stress from the combat they are involved in. They may communicate with the ground troops they are supporting and feel a bond with them. They may also feel helplessness, guilt, exhaustion, or burnout as a response to what they witness remotely. A few may even experience Posttraumatic stress disorder.
On 28 October 2009, United Nations Special Rapporteur on extrajudicial, summary or arbitrary executions, Philip Alston, presented a report to the Third Committee (social, humanitarian and cultural) of the General Assembly arguing that the use of unmanned combat air vehicles for targeted killings should be regarded as a breach of international law unless the United States can demonstrate appropriate precautions and accountability mechanisms are in place.
The Missile Technology Control Regime applies to UCAVs.
Collateral damage of civilians still takes place with drone combat, although some (like John O. Brennan) have argued that it greatly reduces the likelihood. Although drones enable advance tactical surveillance and up to the minute data, flaws can become apparent. The US drone program in Pakistan has killed several dozen civilians accidentally for example. Another example is the operation in 2010 Feb near Khod, in Urozgan Province, Afghanistan. Over ten civilians in a three-vehicle convoy travelling from Daykundi Province were accidentally killed after a drone crew misidentified the civilians as hostile threats. A force of Bell OH-58 Kiowa helicopters, who were attempting to protect ground troops fighting several km away, fired AGM-114 Hellfire missiles at the vehicles.

Famous quotes containing the words laws, war and/or ethics:
“Natural knowledge, seeking to satisfy natural wants, has found the ideas which can alone still spiritual cravings. I say that natural knowledge, in desiring to ascertain the laws of comfort, has been driven to discover those of conduct, and to lay the foundations of a new morality.”
—Thomas Henry Huxley (182595)
“Soldier, there is a war between the mind
And sky, between thought and day and night. It is
For that the poet is always in the sun,
Patches the moon together in his room
To his Virgilian cadences, up down,
Up down. It is a war that never ends.”
—Wallace Stevens (18791955)
“Indeed the involuntary character of psychiatric treatment is at odds with the spirit and ethics of medicine itself.”
—Kate Millett (b. 1934)
