The 9K33 Osa (Russian: 9К33 «Оса»; English: “wasp“; NATO reporting name SA-8 Gecko) is a highly mobile, low-altitude, short-range tactical surface-to-air missile system developed in the Soviet Union in the 1960s and fielded in 1972.
Iraq fielded Osa systems during the 1991 Gulf War. The Russians claimed that it was the most effective system alongside the ZSU-23-4 Shilka at shooting down Tomahawk cruise missiles, with several downings credited to hits from Osa weapons.
