Stanley Allen McChrystal (born 14 August 1954) is a retired United States Army general best known for his command of Joint Special Operations Command (JSOC) from 2003 to 2008 during which his organization was credited with the elimination of Abu Musab al-Zarqawi, leader of al-Qaeda in Iraq. His final assignment was as Commander, International Security Assistance Force (ISAF) and Commander, United States Forces – Afghanistan (USFOR-A). He previously served as Director, Joint Staff from August 2008 to June 2009. McChrystal received criticism for his alleged role in the cover-up of the Pat Tillman friendly fire incident. McChrystal was reportedly known for saying what other military leaders were thinking but were afraid to say; this was one of the reasons cited for his appointment to lead all forces in Afghanistan. He held the post from 15 June 2009 to 23 June 2010.
