"One of these systems, called Cheburashka, has been installed near one of the buildings of the (now apparently former) Donetsk National Technical University," the journalist wrote.
"Either 1) the militants are going to open a Department of Electronics in the seized college, or 2) the Russians have delivered the latest Krasukha-4 electronic weapon system," Tsaplienko notes ironically.
"For information, the Krasuha-4 radio counter-measures system is designed to defend against radar, reconnaissance and drone aircrafts. The station renders various types of aircraft 'deaf and blind'. It can 'turn off' not only radar signals but also control channels of unmanned flying vehicles. It is effective at distances up to 300 km," the journalist wrote.
We note that the OSCE monitoring mission today announced the termination of use of unmanned flying vehicles over Eastern Ukraine. The OSCE decision is explained by the threat of electronic interference by terrorists. According to experts from the mission, it requires specialized military equipment to achieve such interference.
