The era of autonomous weapons has arrived. Today around the globe, at least thirty nations have weapons that can search for
and destroy enemy targets all on their own. Paul Scharre, a leading expert in next-generation warfare, describes these and
other high tech weapons systems-from Israel's Harpy drone to the American submarine-hunting robot ship Sea Hunter-and examines
the legal and ethical issues surrounding their use. "A smart primer to what's to come in warfare" (Bruce Schneier), Army of
None engages military history, global policy, and cutting-edge science to explore the implications of giving weapons the freedom
to make life and death decisions. A former soldier himself, Scharre argues that we must embrace technology where it can make
war more precise and humane, but when the choice is life or death, there is no replacement for the human heart.
