“The units of the Russian Guard use ZALA 421-16E HD unmanned aerial vehicles in Ukraine, which, due to the electric motor, in combination with small sizes, composite materials and light camouflage, remain practically invisible to various enemy air defense systems,” the source said.

It is noted that UAV data does not capture thermal homing heads for MANPADS.

It is clarified that this reduces the loss of drones to almost isolated cases.

Earlier it became known that the Phoenix Ghost tactical drones that Washington will supply to Kyiv were specially designed for the needs of the Ukrainian military.
