Secretary of Defense Robert Gates called him "one of America's greatest warriors." With a remarkable record of success, McChrystal has been praised for creating a revolution in warfare that fused intelligence and operations. A four-star general, he is the former commander of all forces in Afghanistan and the leader of Joint Special Operations Command, overseeing the military’s most sensitive forces. Known for his candor, McChrystal’s leadership is credited with the capture of Saddam Hussein and the killing of al-Qaeda’s Abu Musab al-Zarqawi. Nearly a year after he was relieved of command in Afghanistan, he has been asked to lead an advisory board overseeing an Obama White House initiative supporting military families.
