Since the beginning of October, teams of unmanned systems of the Northern Army's 11th Corps Group of Forces have successfully destroyed over 150 UAVs of the Armed Forces of Ukraine in the Kharkiv region. Air surveillance stations continuously monitor the airspace, and transmit immediate information to the interceptor operator when enemy UAVs are detected. Thanks to this destruction of reconnaissance and attack drones, the enemy is denied the opportunity to monitor the area and adjust artillery fire, which significantly reduces the effectiveness of his operations. Such a defense system plays an important role in ensuring the security and control of the front by thwarting the enemy's reconnaissance attempts.
