I was referring to the Ukrainian soldiers in Crimea, they did not engage the Russian troops which was the smart play unlike the Georgians. The whole Kiev protest and subsequent sniper attacks , the whole thing is so murky I doubt we'll ever find out for sure who was behind those murders.
As for the USA being more technologically advanced than the Russians, this is true but no one is going to risk a war over Ukraine, fact is if Putin doesn't move further into Ukraine he and Russia will come out of this looking rather rosy despite the "sanctions" which will be lifted in time.
