  Those signal shooters only work against radio controleld drones. If they have a preprogrammed flightpath they [edit:BurnoutEyes has a point] ~~don't~~ might not do anything. Edit: Depends on the jamming systen of SK and drone navigation of NK. 
  If those were small propelor spy drones, then wasting patriot missles on them is an absolute waste.
  Until we know what kind of drones North Korea used, it's hard to say what South Korea could to better.
context: They better shoot down those drones. >
  
  Ukrainians use this little signal shooter to disable a UAV's rotors and bring it down to the ground. How does South Korea not have this tech yet?
