The Iraq War, also known as the Second Gulf War, Operation Iraqi Freedom ("US"), Operation TELIC ("UK") or the occupation of Iraq, was a conflict which began on March 20, 2003 with the United States-led invasion of Iraq by a multinational coalition composed of U.S. and British troops supported by smaller contingents from Australia, Poland, and other nations. Five service members have posthumously received the Medal of Honor for actions in Iraq: three from the Army, one from the Marine Corps and one from the Navy. Army Staff Sergeant David Bellavia is currently the only living recipient of the Medal of Honor for his service during the Iraq war.
