President Obama authorizes 1,500 more troops for Iraq

Today our President authorized an additional 1500 more troops to Iraq to battle ISIS. If all 1,500 are deployed, it would almost double the American presence in Iraq. The troops will serve in a non-combat role, expanding the U.S. mission of training and advising Iraqi forces, the "Pentagon said". That will include helping Iraqi forces in the highly volatile section of Anbar Province mostly under ISIS control. As reported by NBC.

So have we passed the point of continually stating "no boots on the ground"? And if our troops are in a high volatile section controlled by ISIS are we really non-combat? Are our troops under any ROE's or are they under direction to not respond to any action that may put them in harms way?

I think we are getting close to the point of no return and the inevitable fight we really don't want to start in country again. Not that it has really ever stopped.
