9k33 osa (rs-sa-8 gecko)

The 9K33 Osa (NATO reporting name SA-8 Gecko) is a highly mobile, short-range tactical surface-to-air missile system developed in the Soviet Union. It is notable for being the first mobile SAM system to integrate all its engagement radars and missiles onto a single amphibious vehicle.

Initiated in 1960 to protect motorized rifle divisions from low-flying aerial threats, the system officially entered Soviet service in 1971 after a prolonged development cycle. It saw its first major combat deployment during the 1982 Lebanon War and has since been utilized in numerous global conflicts, including the Gulf War, the Nagorno-Karabakh wars, and the ongoing Russo-Ukrainian War. Today, the system remains in active service with over a dozen nations, having undergone various modernization programs to upgrade its radar and missile capabilities to counter modern precision-guided munitions.
