COIN is the only low and slow CAS mission the Americans are going to fly at this point, as if you tried to fly the A-10 or any other jet low and slow against a near peer, they'd get shredded; flying an A-10 against the 1st Guards Tank Army with its IADS consisting of Panstyr, Tor, BUK, S-300V, and S400, would be a suicide mission.
If the Russians came roaring through Belarus into Lithuania and Poland, the current inventory of A-10's wouldn't last a week, too slow, too low, it's just not a survivable aircraft in the contemporary SAM/Radar paradigm, already at the threshold now, where flying low and slow CAS manned against a combined arms formation is basically obsolete, stand off precision guided weapons is the only viable option, unless you're talking low threat environment as per COIN.
That being said, AT-6B is too small even for COIN, the COIN plane is the AT-29B Super Tucano.
The way the Russians actually fight, artillery based army with massive indirect fires protected by layered mobile armored IADS, the most important weapon in the NATO fire support inventory would be the MLRS, not the A-10. If you want to kill Russian tanks, the best way to do it is MLRS launched top attack anti-armor submunitions, flying the A-10 at them would just get pilots killed to no particular utility.
