Death from above: watch Ukraine’s Vampire drone take on Russian troops

By its nature, drone warfare has a huge wastage rate. The Royal United Services Institute think tank estimated last year that Ukraine’s armed forces were getting through about 10,000 drones a month. Some are electronically jammed and crash, or are shot down. Others are the one-way kamikaze FPVs which, in just 15 months, have emerged from prototypes based on hobbyists’ drones to dominate the forward edges of the front.
