This has been covered already in this thread, and there are two good arguments:
1. The USAF does not want to ditch the A10. Bean-counters within the civilian parts of the Department of the Air Force want to ditch the A10.
2. Getting A10s to Ukrainians would not be difficult. Training Ukrainian pilots to employ them properly would be very, very difficult. And keep in mind that A10s are designed to work within an air-superiority framework that the USAF can provide, but the UAF cannot.
This is precisely why so many posters here are assuming there's more going on here. I am not a tinfoiler, but it VERY MUCH stands to reason that guys in Tier One units might well be futzing around in Ukraine already.
In Kosovo, we called them OGAs, "other government agencies." There might or might not have been a team of them living on the top floor of the building I was billeted in, and they might or might not have worn sanitized uniforms. And this was almost 25 years ago.
I don't know how long they'd [hypothetically] been in that city, but they were [hypothetically] there before we were. And my battalion was nominally the first US Army unit in Kosovo.
