DARPA drone interceptor seems to be armed with a form of Silly String

Jack Watling of UK defence think tank RUSI says that the streamer-firing interceptor appears conceptually sound, but the reliability and cost of the system may still be issues. From a military viewpoint it has only one function; unlike most weapons it cannot be used against other targets, which may make it unpopular, he says. “I would be surprised if this particular concept becomes widely fielded within the military.”
