The Russian Armed Forces deployed the second unit equipped with S-400 air defense systems in the Republic of Crimea, the Russian state-run media reported on Saturday. On the same day, the 12th Anti-Aircraft Missile Regiment, deployed south of the city of Sevastopol, became fully operational.
In 2017, the 18th Guard Anti-Aircraft Missile Sevastopol-Feodosia Regiment received S-400 air defense systems. Thus, now, two units of the Russian Armed Forces deployed in Crimea operate the S-400.
