Petraeus reached the level of four-star general in the Army and rose to national prominence in 2004, after he was named as field commander of the transition command team in Iraq, where he had been serving as leader of the 101st Airborne Division. Three years later, President George W. Bush named him as the commander of all U.S. troops in Iraq.
He retired from the Army in August of 2011, the same month that Obama nominated him to head the CIA.
