Good God, wow.
One case where we really got what we paid for.
With air superiority for the U.S. and adequate numbers of aircraft and artillery present you have to be insane to attack U.S. forces head on. I think there was obviously some miscommunication on the Russian end of this as they did not appear to realize their “mercenaries” were part of the attacking force.
Mattis knows his business. I wish he would fumigate the PC crap from the military, but we can at least be confident that he will aggressively act when necessary.
