Since the U.S. began drone warfare in Afghanistan in 2001, drone attacks have been undertaken in Afghanistan, Pakistan, Yemen, Somalia, Iraq, Libya, and possibly in Syria.
About 6,000 people have been killed by US Drones in Pakistan, Yemen, Afghanistan, Somalia, Afghanistan, Iraq and Libya, according to estimates provided by the Bureau of Investigative Journalism, the foremost independent monitor of drone war casualties. Of this total up to 230 are children killed in Pakistan, Yemen and Somalia, according to Bureau statistics. The Bureau does not have an estimate of women killed in these countries or across the whole drone war. But judging from what little is known of women being killed in drone attacks and the international scope of the drone attacks, it appears that many women have been killed, probably numbering in at least the hundreds. It is impossible to know with any certainty how many people have been killed by U.S. drones. The U.S. has withheld all information on the extent of the drone attacks, and drone attacks occur in very remote areas, making independent accounting difficult and grossly incomplete.
Drones flown out of Beale AFB are "accomplice drones." Global Hawk drones controlled from Beale are used in the targeting of Predator and Reaper attacks. The 48th Intelligence Squadron at Beale AFB processes information gathered by the MQ-1 Predator, MQ-9 Reaper and RQ -- Global Hawk drones to permit attacks by U.S. forces worldwide. Predator and Reaper drones are not flown from control centers at Beale.
At least 100 Predator and 200 Reaper drones are believed to be operating now; exact figures are not available. At any given moment the U.S. has at least 180 Predator and Reaper drones in the air; 60 combat patrols, comprised of three drones each. The Air Force wants to increase the number of constant combat patrols to 65, putting 195 drones in the air at any given time.
As of December 2013, there were about 1,350 drone pilots in the U.S. Air Force, according to an April 2014 Government Accountability Office (GAO) report, which said that the Air Force had not been meeting its recruiting goals for drone pilots. Further, more drone pilots are quitting than can be trained, as reported by TomDispatch on March 26, 2015, which said the Air Force would like to have 1,700 pilots to cover the 65 combat patrols. A key factor in the attrition is said to be over work, increasing even more as missions expand in Iraq, Libya, and Syria. It appears likely that the stress is also leading to mistakes being made, further endangering those under surveillance.
The GAO report says that the U.S. Air Force "has not fully analyzed" the "stress" faced by pilots who go home every day after flying missions. The report said: ""pilots in each of the 10 focus groups (which included Beale pilots)"reported that being deployed-on-station (going home every day) negatively affected their quality of life, as it was challenging for them to balance their warfighting responsibilities with their personal lives for extended periods of time."
