NYDN: "Hellfire homed in on terrorists cell phone"
Ok, the title for the article is technically inaccurate. Hellfire missiles home in on laser beam reflections. Still, the article provides additional detail on how the Predator managed to find those terrorists in Yemen a couple weeks ago.
Still, I can't help but think this info shouldn't have been released. Unless it's disinformation, you shouldn't tell everyone how we can do these things.
