30mm 96K6 Pantsir-S1 (RS-SA-22 Greyhound)

The Pantsir missile system is a family of self-propelled, medium-range surface-to-air missile and anti-aircraft artillery systems. Three types of vehicles make up one system: a missile launcher, a radar truck and a command post. Starting with the Pantsir-S1 as the first version, it is produced by KBP Instrument Design Bureau of Tula, Russia, and is the successor to the tracked Tunguska M1 system. 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.

Developed by the KBP Instrument Design Bureau starting in 1990, the system was designed to succeed the Tunguska-M1 and provide close-in defense for long-range air defense systems like the S-300. Development was delayed by post-Soviet economic struggles until funding from the United Arab Emirates revived the project, leading to its official entry into Russian service in 2012. The Pantsir-S1 has seen extensive combat deployment in the Syrian Civil War, the Libyan Civil War, and the Russia-Ukraine conflict, where it has engaged various unmanned aerial vehicles and precision-guided munitions. It remains a key component of Russia's layered air defense network, with ongoing upgrades focusing on countering modern drone swarm tactics.
