For nearly a decade, Brett Velicovich was at the center of America’s new generation of warfare: an arsenal of unmanned aerial vehicles—drones—taking down the world’s deadliest terrorists across the globe. Now this decorated veteran, with journalist Christopher S. Stewart, tells his story in a remarkable book packed with more classified drone operations cleared for public release than any other account ever published, according to the U.S. government. Drone Warrior offers an unprecedented view into the remarkably complex nature of drone missions in the hottest conflict zones today and the rigorous and wrenching on-the-ground decisions behind them.

Drone Warrior also chronicles the U.S. military’s evolution in the past decade and the technology driving it. Velicovich considers the future it foretells, and speaks candidly on the physical and psychological toll it exacts, including the impact his missions had on his own life. He reminds us that while these machines can kill, they can also be used to preserve life, including protecting endangered species and supporting humanitarian operations—work he is engaged in today.
