Start Of Operation New Dawn

U.S. combat operations in Iraq have come to an end and as President Barack Obama said it's time to turn a page.

Wednesday morning Defense Secretary Robert Gates arrived in Iraq joining Vice President Joe Biden to formally bring combat operations to a close.

Right now officials said there are roughly 50,000 American forces in Iraq to begin Operation New Dawn.

The mission: advising and supporting Iraqi security forces over the next year.

"They've gotta be successful really early on," (Ret.) Major Mike Lyons said. "The next 90 days will tell whether or not the Iraqi security forces have been successful and been trained well."

Obama promised the U.S. wouldn't just walk away from the country, saying the combat mission is ending but our commitment to Iraq's future is not.
