If I were the Russians, if possible, I’d absolutely plaster (short of the NBC threshold) the first unit that was in country.
There is NO way they’d want foreign units in the battle.
For 75 years this has been our worst nightmare, Americans and Russians killing each other on the battlefield, no proxies involved. A nightmare because everyone knows where that ends. Now, people read this disinfo horse crap for a month and think regime change in Moscow will be like regime change in Baghdad. My prepper plans are half assed, at best. I’ll probably regret that greatly.
