“The units of the advanced S-400 missile systems entered combat duty for the air defense of military, administrative and civil facilities,” the report says.
The units reportedly received the new systems from representatives for the manufacturing facility at the Kapustin Yar Range in the Astrakhan Region. After the live firing the units marched more than 2,000 km in the Leningrad Region.
