US Changes Military Commanders In Iraq

The final phase of the U.S. military involvement in Iraq -- the post-combat phase -- is under way. The transition officially took place with a handover of the U.S. military command there to Army Gen. Lloyd Austin. He'll now lead about 50,000 U.S. troops who remain there, with a deadline for a full pullout by the end of next year.

As he takes command of U.S. troops in Iraq, Austin notes that "hostile enemies" still threaten that country. And he says the U.S. commitment to Iraq "will not change." Vice President Joe Biden told assembled U.S. and Iraqi dignitaries and troops that the transfer of authority from Gen. Ray Odierno to Austin symbolizes a "different chapter in the relationship with Iraq."
