The SA-7 Grail, also known as the 9K32 Strela-2, is a portable surface-to-air missile system developed by the Soviet Union in the 1960s. Designed for use by infantry, it is lightweight and can be easily carried and launched by a single soldier. The missile is guided by infrared homing, allowing it to target low-flying aircraft effectively. The SA-7 Grail has been widely exported and used in various conflicts around the world. Its effectiveness against helicopters and fixed-wing aircraft has made it a significant threat to air operations. Variants of the missile have been produced, and it remains in service with several countries today.
