The federal highway 70 leads a few hundred meters northwards, out of the village of Meppen in Emsland. Then a road branches off to the right into the forest, the name of which says it all: shooting range. Here the tests weapons and ammunition on a huge forest and heather area. Signs warn: “Military security area.” Photo and video recordings are strictly prohibited, as are flights over the firing range. On this June day, however, the hum of drones can be heard over the restricted area for hours. The pilots steer their planes sometimes in low flight over the heather, sometimes covered between trees and bushes. They are supposed to outsmart the air defense systems whose manufacturers invited the troops to test it at short notice. In the Middle East, terrorists use drones from electronics stores as flying grenade launchers.
