Waldman charts it:
At the beginning of last year, the armed forces had 7,500 drone aircraft, meaning that one out of every three flying machines in the military was a drone (though the majority are the small, hand-launched kind). The Pentagon is considering scaling back on procurement, on the theory that it has about enough drones for the near future. But that doesn’t mean they’re becoming less important; quite the contrary. The military has even created a medal you can win for piloting a drone; it will rank above the Bronze Star, despite the fact that you can earn it without any risk to life or limb.
