That argument has been kicked around for decades without success. The Army is neither funded or equipped to train A-10 pilots or support the airframes and the Army leadership doesn’t want the airframes for those reasons. The Air Force needs to be forced to do its close air support role with the (proven) airframe it originally convinced Congress to fund and support over 40 years ago or be re-integrated as a force back into the Army.
That’s a good argument. Thanks.
