two groups of commandos captured, one of which has an African-American

I think this is unlikely. No sense in sending “commandos” who are black in a largely white country, especially for stay behind. The fact he’s claimed black is probably a Russian attempt at authenticity. But the main theme of the disinformation is that ‘America has planned this’, etc. So while I don’t know if for a fact, I would discount.

It’s now about dawn in Georgia right now, FWIW.
