@lakoma I don't need any source - I've been following the war since 2013. The Russians have destroyed it. Do some homework and by that I mean real news, not propaganda you'll get from all the western MSM. The US military has even said that they can't provide new air defence other than a few complexes. The US and NATO don't have good air defense, at lesat not as good as Russia's. None of the western media is reliable when it comes to war, NATO and the ColdWar 2.
