SA-19 Grison (9M311 Treugolnik) Country: Russia Type: Point SAM Introduction: 1988

The 2K22 Tunguska is a Russian tracked self-propelled anti-aircraft weapon armed with a surface-to-air gun and missile system. It is designed to provide day and night protection for infantry and tank regiments against low-flying aircraft helicopters and cruise missile in all weather conditions. Its NATO reporting name is SA-19 Grison.

Development of the system started in 1970. The project was a response to the observed shortcomings of the ZSU-23-4 (short range and no early warning) and a counter to new ground attack aircraft in development. Development slowed between 1975 and 1977 after the introduction of the 9K33 Osa missile system. It was officially accepted into service on the 8th September 1982 and the initial version designated 2K22/2S6, with four missiles in the ready to fire position (two on each side). The system uses the 9M311 (NATO: SA-19/SA-N-11) missile family.
