| A Marine and a Navy medic killed by a U.S. drone airstrike were targeted when Marine commanders in Afghanistan mistook them for Taliban fighters, even though analysts watching the Predator's video feed were uncertain whether the men were part of an enemy force. Those are the findings of a Pentagon investigation of the first known case of friendly fire deaths involving an unmanned aircraft, the April 6 attack that killed Marine Staff Sgt. Jeremy Smith, 26, and Navy Hospitalman Benjamin D. Rast, 23. |
