A gaggle of A10's only work well when there is sufficient Air Superiority or beter Supremacy.
if all you have, at best , is air Parity, a gaggle of A10's would soon be a smoking hole in the ground.
Right now, the Russians have pretty decent Air Superiority over Ukraine.. they are flying with very little interference by the Ukrainians. Ukrainians aren't able to send up much, nor can they expect to fly when and wherever they please.
