CHANGE: Pentagon sends attack helicopters to Iraq.

The United States has sent Apache attack helicopters to Iraq as part of the buildup in U.S. military personnel, the Pentagon said Tuesday.

Officials would not say how many of the armed helicopters have been sent to the country, stating only that they will be based in Baghdad and could assist with evacuations of American personnel.

The Pentagon also sent over additional surveillance drones.

President Obama on Monday sent 200 additional U.S. troops to Iraq to protect diplomatic facilities and personnel amid growing fears that Sunni militants in the Islamic State in Iraq and Syria (ISIS) could overrun the country. The order brought the total number of U.S. ground forces in Iraq to 750.

On Monday, the State Department announced it was relocating some of its personnel from Baghdad.

Sounds like a bang-up approach.
