Think of it as a guided hand grenade. On the battlefields of Ukraine, small, cheap drones constantly fly over opposing lines. If an enemy soldier is spotted, the drone pilot no longer attempts to drop an explosive: he simply pursues the poor devil — down trenches, around trees and straight into a reinforced bunker —until the FPV (First Person View) drone makes contact with its target and explodes. Horrifying. And more than 90% fatal once a target has been spotted.
