That is my understanding too. They are to be used as a more lethal version of the SkyTractor’s that are being employed now by some of our allies. I am over here in the ME and have been able to actually look them over. In any event, they are not an A-10.
I'm partial to the AT-6
These aircraft are cheaper to operate and can respond faster than the A-10 in many circumstances.
The ability to respond quickly to disrupt and break up an attack or ambush as soon as possible after contact is a nice thing to have and these smaller aircraft can provide that sort of support and then stick around to act as FAC for larger aircraft or artillery support afterwards
