It's nearly impossible to discuss the future of autonomous military robots without thinking of the 1984 movie, "The Terminator." The sci-fi thriller portrayed a futuristic war waged among the remnants of civilization and an antihuman army of robotic tanks, planes and (of course) cyborgs with laser guns.
Are terminators real?
You won't see mechanized humanoid soldiers on the battlefield soon, but robotic air and land units are here. Thousands of them aid in disarming bombs, and a variety of surveillance drones soar the skies, ranging from the handheld RQ-11 Raven to the 44-foot (13.4-meter) RQ-4 Global Hawk. And yes, some of them pack heat.
