Russian S-300 missile systems performed combat launches during air defense drills of the Western Military District at the Ashuluk firing range near the southern city of Astrakhan, a spokesman for the district, Igor Muginov, said Thursday.

"According to the drills scenario, the S-300 air defense systems were countering a sudden massive missile attack of the simulated enemy," Muginov said.

He added that the exercises ended with practicing the most complex element of the combat training, namely, the destruction of a simulated target moving along a ballistic trajectory. Simultaneously, the positions of the S-300 units were attacked by six of these targets, all of them were successfully destroyed.
