While officially in use by the United States since the Vietnam War, they entered American public consciousness during the wars in Iraq and Afghanistan and bore the brunt of American offensive operations in other realms of “Overseas Contingency Operations” (OCO) like Pakistan and Yemen, mostly against unarmored mounted and dismounted targets without anti-air capability. As such, they have become the near-perfect weapon for counter-terrorism (i.e. killing high-value targets) in the 21st Century.
In popular culture, they were featured in 2003’s Terminator 3, chasing John Connor and Claire Danes down the hallways of Skynet and are a useful and easy to obtain kill streak reward in the Call of Duty video game franchise. Additionally, in the past few years articles warning of the dangers of their use by local police have become more common.
Today, Iraq may be the drone capital of the world with drones in its skies currently operated by the US, UK, Australia, Iran, Islamic State, and of course the Iraqi military itself. It is difficult to find accurate numbers (if any numbers at all) of drone sorties flown by these actors and compare them to other countries, but if Iraq is not the drone capital by volume then surely its diverse drone community makes it the de facto capital.
