It does. Russia is winter ready. And you’re right. They used the tried and trusted Soviet weaponry, built to last, but only to preserve the new weapons the West hasn’t even seen yet. Those Missiles on the back of enormous trucks being lowered into silos across Russia remind me of the NASA rockets approaching the launch pad. And also according to Brian at The New Atlas on YT, to keep the newer weapons away from prying eyes so that the West don’t learn their capabilities and counter them. The EU have depleted their stockpiles of weapons and even the US claim the same. Who knows? I bet the Russians do.
