Strela-3 is a portable surface-to-air missile system developed by the Soviet Union in the 1970s. It is designed to target low-flying aircraft and helicopters, providing ground forces with a means to defend against aerial threats. The system is lightweight and can be operated by a single soldier, making it suitable for various military operations. The missile has a range of approximately 3.5 kilometers and uses infrared guidance to home in on its targets. Strela-3 has been widely exported and used by many countries, contributing to its reputation as a reliable short-range air defense system.
