Well, they absolutely can with a BRRRRT, but if you mean "AGM 88 HARMs are a poor weaponeering choice against a Misagh-3", then sure, no argument here. But a dude on a hilltop with a shoulder tube is not the only type of air defense.

I'm not sure why any of this is relevant. The question I was responding to was about why A-10s are even in-theatre, given there's no boots on the ground yet.

The answer to that question is "they're probably doing SEAD". They might also be there to hit Iranian naval drones, though I doubt it'd be effective in that role.
