Patrick Daniel Tillman (November 6, 1976 – April 22, 2004) was an American football player in the National Football League (NFL) who left his sports career and enlisted in the United States Army in June 2002 in the aftermath of the September 11 attacks. His service in Iraq and Afghanistan, and subsequent death, were the subject of national attention when he was killed by friendly-fire.Tillman joined the Army Rangers and served several tours in combat before he was killed in the mountains of Afghanistan. At first, the Army reported that Tillman had been killed by enemy fire. Controversy ensued when a month later, on May 28, 2004, the Pentagon notified the Tillman family that he had been killed by a friendly fire incident; the family and other critics allege that the Department of Defense delayed the disclosure for weeks after Tillmans memorial service out of a desire to protect the image of the U.S. military.
Tillman was the first professional football player to be killed in combat since Bob Kalsu, who died in the Vietnam War in 1970. Tillman was posthumously promoted from specialist to corporal. He also received posthumous Silver Star and Purple Heart medals.
