The Russian Armed Forces are actively rearming its units with the new advanced Buk-M3 surface-to-air missile system. The newest Russian 9K317M Buk-M3 medium-range surface-to-air missile system (NATO reporting name: SA-17 Grizzly) entered in service in 2015.
The new type of missile used by the launcher is more compact than the previous versions. This allows Buk-M3 to carry a payload of six instead of four missiles. The new missile also outclasses previous models in technical characteristics. The missile can destroy any type of airborne target in existence, can be used against naval and ground targets and it is resistant to electronic.
Just pile them up all around the Russia. The more the better. Only those very effective defensive weapons (and fear they create) are the last line of protection to preserve fragile peace. There are raving lunatics in US, on very high positions, looking for the possibility to destroy whole planet.
