Russia cant go up against Javelin - no armor in the world canNo one is afraid of Russia's conventional army any more.. They have shown themselves to be inept. They can't project themselves much farther than rail lines go and rail lines are easy targets. They still have not achieved air superiority over Ukraine. If Putin decides to use nukes he will shortly there after die. One Polaris armed sub could take out every major city in Russia. If Russia nuked the US it would piss the sub commanders off and they would certainly launch missiles. I doubt Putin or his Generals will risk mutual destruction .
Their AF has MANPADS, S-300, and Buk-M1 surface-to-air missile system
Also we sent them Stingers.. it's not Russian inferior weapons.it's the top quality weapons we sent in our war against russia
