"A riveting account of one of the most significant developments in contemporary warfare – the evolution and proliferation of drones. This is a very important book." – General David Petraeus, US Army (Ret.), former Commander of the Surge in Iraq, US Central Command, and Coalition and US Forces in Afghanistan, and former Director of the CIA
A report revealed that drones were used to monitor protests in the US. “Remember that drone in Minneapolis? It was part of a nationwide operation that sent helicopters, airplanes and drones over 15 cities where demonstrators gathered to protest the death of George Floyd, logging at least 270 hours of surveillance.”
