Um, I'm pretty sure you mean the Iraqi 9th Armored Division, the US 9th Armored Division isn't even active anymore and no US ground troops are even deployed to Iraq right now.
There is no such thing as 'defeating whole division' unless the entire division are casualties or are captured as well with the collapse of the rear & service/support units.
A better description is 'inflicted material losses and casualties'. And yep, US 9th Armored is not in Iraq.
Yeah 9th armored was in ww2 or something. And unless the US government has been lying about our non involvement vs ISIS (which wouldn't be surprising cuz our government lies about pretty much everything unfortunately) those pictures are almost certainly of a victory over the Iraqi military, which was provided with state of the art US vehicles and weapons. Too bad they're all giant pussies and peace out instantly.
