He elaborated that no „fancy“ systems are needed for this and that the quite simple and battle-proven Russian Pantsir S1 (NATO reporting name SA-22 Greyhound) systems with dual 2A38M 30 millimetre automatic cannons equipped with infrared direction finders would do the trick. Russia has been successfully using Pantsirs to repel frequent massive drone attacks on its Hmeymim base in Syria carried out by local militant groups.
