The Russians just shipped a dozen SU-25's (Russian A-10 equivalents) to them. But that's just a dozen. Coalition forces had access to hundreds of fixed-wing combat aircraft, and they spent very little time parked.
Thanks for the up-date. Our operations were against a large and on paper anyway powerful state military. I am still trying to figure out what makes ISIL so powerful. I guess it is just the regional religious tribalism that lends the weight of the indigenous populations to a relatively small group of fighters.
