Warfare is no longer about dumping thousands of men in a field and shooting at each other. Today, non-governmental forces are packing explosives onto commercially available drones and flying them over crowded areas.

While this attempt was unsuccessful, it marked the first time -- but almost certainly not the last -- that a paramilitary organization tried to assassinate a sitting head of state with a drone.
