Fantastic Lad writes to tell us that journalist Michael Hanlon recently got the opportunity to experience the Army's new not-so-secret weapon, dubbed "Silent Guardian". The Silent Guardian is essentially (even though the creators prefer you not refer to it as such) a ray gun, emitting a focused beam of radiation similar to your microwave tuned to a specific frequency to stimulate human nerve endings. "It can throw a wave of agony nearly half a mile. Because the beam penetrates skin only to a depth of 1/64th of an inch, it cannot, says Raytheon, cause visible, permanent injury. But anyone in the beam's path will feel, over their entire body, the agonizing sensation I've just felt on my fingertip. The prospect doesn't bear thinking about. "
