The Ruskies have always invested in & created capable air-defences to balance out the West's air superiority.The S-300 evolved around the same time as the PAC-2 & is often rated as better than the Patriot(given it's miserable performance in Desert Storm).

Understand.
The PAC 2 sucked in Desert storm. THe PAC 3, however, saved my ass several times during the first few days of the war during OIF.
