A rapid Ukrainian advance in Kursk has taken Russia by surprise, pushing deep into enemy territory. The successful offensive is attributed to Ukraine's mastery of electronic warfare and drone technology. According to reports, Ukrainian forces brought down Russia's reconnaissance drones using new interceptor FPVs linked to air-defence radar, then deployed short-range jammers to disrupt Russian communications. This allowed Ukrainian armor to cross open terrain without being destroyed.
