Halo announcer: Overkill! General Perkins, commander of the US Army Training and Doctrine Command, would have you know that he believes in electronic warfare and cyber measures as the preferred means to take down drones, but that doesn’t change the fact that there are others out there who are willing to take extreme measures in blowing them out of the sky, like using radar-guided missiles that cost millions of dollars. We've heard about people shooting down drones buzzing over their property, but this takes things to a whole new level: A store-bought quadcopter drone has been shot down by a Patriot surface-to-air missile. "That quadcopter that cost 200 bucks from Amazon.com did not stand a chance against a Patriot," said Gen. David G. Perkins, commander of the US Army Training and Doctrine Command, in a speech posted to YouTube on Monday by the US Army and first reported by the BBC. The missile wasn't fired by the US, but by someone Perkins described as an ally "dealing with an adversary," suggesting it wasn't a test.
