You know if Russia were in a last ditch battle for survival I might think they could muster some amazing performance. Trying to be the baddies in another person's country -- at gunpoint -- next to felons. Yeah, I'm not seeing any improvement in Russian battlefield performance. Now, throw in the fact that their industrial base is a joke and they can't even pay to keep their vaunted space launch capability at Baikanur (Kazakhstan is foreclosing on stuff Russia has defaulted on at the space station there).
Russia is screwed. Now, throw in the fact that the best or near best western gear is coming. It will have modern C4ISR systems not handheld motorola bricks but actual tactical communications gear. It will have depleted uranium shells. It will have Mirage 2000, F-16s, Patriots backing it up. Yeah, I'm liking Ukraine's chance of recapturing Crimea.
