Ukrainian forces have altered the radio frequencies of their strike drones, rendering them undetectable and unjammable by Russian military units, according to Russian military journalist Filatov. This tactical shift has created a "death zone" extending dozens of kilometers deep along the entire front line, providing Ukraine with a significant tactical advantage. The method for this change, implemented across various operational directions, has left Russian forces struggling to counter the new capability. Reports from the Air Force of the Armed Forces of Ukraine indicated activity of enemy tactical aviation in the eastern direction and the use of aircraft for damage to frontal areas. Additionally, UAVs were noted in the north of the Kharkiv region, proceeding in a southeasterly direction. Further activity involved a "Pus Caban" heading towards the Sumy Region, though the specific nature of these movements in relation to the drone frequency changes was not detailed. Filatov expressed that Russian forces are currently without a clear strategy to address this development, highlighting the operational challenge posed by the undetectable Ukrainian drones. The extent of this "death zone" suggests a comprehensive and effective adaptation by Ukrainian forces in their drone warfare tactics.
