At the end of December, the new S-400 Triumph arrived at the permanent deployment point in the Moscow region from the Kapustin Yar training ground in the Astrakhan region after the successful conduct of initial combat firing by the combat calculations of the division.

Combat crews have prepared anti-aircraft missile systems and technical positions for combat duty on air defense in the established area of responsibility.

Currently, the air defense of the city of Moscow and the central industrial district of Russia as part of the air defense units of the VKS is provided by five anti-aircraft missile regiments equipped with the S-400 Triumph air defense system.

NOTE: there are 8 regiments employed around Moscow so if 5 are S400 then one assumes the other 3 must be S300PM's

Combat crews of the S-400 Triumph and S-300 Favorit anti-aircraft missile systems (SAMS) of three air defense units of the Central Military District (CVO) deployed firing positions in new areas during a tactical exercise launched in three regions of Russia.

The military personnel of the air defense formations stationed in the Saratov, Novosibirsk regions and the Republic of Khakassia have withdrawn the air defense systems from the attack of a conditional enemy and deployed firing positions in new duty areas.

During the tactical exercise, the S-400 "Triumph" and S-300 "Favorit" combat crews will work out the interaction of two types of air defense systems in a single air defense system and perform about 30 combat training tasks to repel air raids by a simulated enemy on critical military, industrial and administrative facilities of the regions.

The exercise of the air defense forces, which will end at the end of the week, is attended by about 1,000 military personnel from combat crews, command posts and management officers, more than 200 units of weapons and military equipment are involved.
