How US media cover US war on ISIS

It is amazing: now that the US forces have picked up the fight on ISIS (and the war on one bad guy) the entire army of US media cover the development with great enthusiasm. But their coverage of Russian war on ISIS have been quite slanted: they basically refuse to even concede that Russia actually launched raids on ISIS. Notice that the war near Aleppo which dislodged ISIS from a key strategic airport was left uncovered because 1) they don't want to acknowledge that Russia fights ISIS; 2) they don't want to concede that this was a  case in which the enemies of the Syrian regime retreated.
