It appears that several dozen squadrons of A-10’s need to be activated and positioned in the Baltics to counter any Russian assault. No doubt Ruskie tanks would be a major element of the Russian assault.
For the last many decades in every so-called war we have fought, we have enjoyed unquestioned air-superiority. I don't know that it is a foregone conclusion we will have air superiority over an area that the Russians decide to invade. It will certainly be a hotly contested issue.
The notion that we would fight Russia over the Baltic states is absurd.
As is NATO, which has not existed in any meaningful sense in 25 years.
New Russian Tanks like the (now obsolescent) T-90 and brand new T-14 Armata have anti-air missiles and radar guided heavy machine guns purposefully designed for just such a situation - the A-10s would be all shot down in the first 15 minutes.
Most of our weapons are no match for the Russians - outranged, outgunned is no joke - our PC top brass likes very expensive weapons that do everything but nothing well, so we lag behind in building new weapons while upgrades are at the mercy of the expensive new toys (aka F-35, littoral combat ships).
