You obviously haven't watched half of what DARPA turns out. I applaud their ingenuity, but I've yet to see anything come out of there that was practical OR not stolen from someone else. I vaguely remember them "inventing" the flechette for use in the 70mm "Hydra" rocket and other sub-munition capable platforms, with the design team receiving an award for their "accomplishment." Shadowrun tech is far ahead on this curve anyways, with the Arsenal Dragonfly suicide drone.
