Home from the War Zone

At the height of the War in Iraq, there were 170,000 U.S. troops stationed in Iraq.  As of today, there are 6,000 American troops and four U.S. military bases still operating inside the country.  All of those bases are located south of Baghdad.  Soon, they will be dismantled and the troops will return home.  Kyra Phillips talked to some servicemen and women who's already returned to the United States.  They told her about their experiences in Iraq, for better and for worse.
