NATO has supplied Ukraine with jammers to defend against Russian drone attacks, the alliance's Secretary General Jens Stoltenberg said in Brussels on November 25. "Allies are providing unprecedented military support," Stoltenberg said, listing deliveries of fuel, medical supplies, wind equipment, and the drone jammers. Jammers are designed to help Ukraine fend off attacks from drones targeting the country. The drone defense is part of wider air-defense systems NATO has provided to defend against Russian aggression.
