2010: The last American combat brigade, the 4th Stryker Brigade, 2nd Infantry Division, withdraws from Iraq, bringing an end to Operation Iraqi Freedom. About 50,000 American troops would remain in the country in an advisory capacity under a new mission dubbed as "Operation New Dawn" before full troop withdrawal was completed in December 2011.
