On November 30, Russia’s Southern Military District’s press service announced that a Pantsir-S air defense battalion had deployed to Crimea earlier in October. According to the statement, these missile systems are “part of the programme to re-equip the district’s troops.” Pantsir-S (SA-22 “Greyhound”) is a self-propelled anti-aircraft gun and missile (SPAAGM) system that can hold up to twelve missiles and two automatic anti-air cannons. The system uses phased-array radars for target acquisition and tracking. This press statement follows Russia’s announcement on November 29 that it deployed a fourth S-400 missile battalion in Crimea. On November 25, Russia seized three Ukranian navy vessels off the Crimean Peninsula, escalating tensions.
