You are PROBABLY right. Just tell me who and when did compromised it.
Please, bring any facts or it looks like you are spreading liberal lies aka ‘soviet junk myth’.
I think it’s clearly shown that the USSR era weapons are entirely ECM’d.
You’re going to accuse me of liberalism? When I’m saying our ECM wrecks Russian stuff? Israel’s attacked Syria in the last few weeks that were defended with s-300s and were in and out. I’m not going to google the other Israel ECM overrides for you though. The latest one is enough.
