The Pantsir (Russian: Панцирь, lit. '"Carapace"') missile system is a family of self-propelled, medium-range surface-to-air missile and anti-aircraft artillery systems. Starting with the Pantsir-S1 (Russian: Панцирь-С1, NATO reporting name SA-22 Greyhound) as the first version, it is produced by KBP Instrument Design Bureau of Tula, Russia, and is the successor to the Tunguska M1.

The Pantsir-S1 was designed to provide point air defence of military, industrial and administrative installations against aircraft, helicopters, precision munitions, cruise missiles and UAVs; and to provide additional protection to air defence units against enemy air attacks employing precision munitions, especially at low to extremely low altitudes.
