FILE - This July 27, 2012 file photo shows Gen. Lloyd Austin, vice chief of staff for the U.S. Army, talking to reporters at Fort Riley, Kansas. President Barack Obama has tapped Austin, the general who oversaw the final troop withdrawal in Iraq to direct the end of the U.S. combat role in Afghanistan. Austin, currently vice chief of staff of the Army, would become the next top U.S. commander for the Middle East if the Senate confirms his nomination. Austin would be the first African-American general to lead U.S. Central Command. (AP Photo/John Milburn, File).
