The 9K32 Strela-2 (Russian: Cтрела, "arrow"; NATO reporting name SA-7 Grail) is a light-weight, shoulder-fired, surface-to-air missile (or MANPADS) system. It is designed to target aircraft at low altitudes, with passive infrared homing guidance and destroy them with a high explosive warhead.
Broadly comparable in performance with the US Army FIM-43 Redeye, the Strela-2 was the first Soviet man-portable SAM – it entered use in 1968, and full-scale production began in 1970. While the Redeye and 9K32 Strela-2 were similar, the missiles weren’t identical. Nonetheless, the CIA concluded that the Soviet SA-7 had benefited from the Redeye’s development.The Strela-2 was a staple of the Cold War and was produced in huge numbers for the Soviet Union and their allies, as well as revolutionary movements. Though since surpassed by more modern systems, the Strela and its variants remain in service in many countries, and have seen widespread use in nearly every regional conflict since 1972.
