Operation Phantom Thunder began on 16 June 2007, when Multi-National Force-Iraq launched major offensive operations against al-Qaeda and other extremist terrorists operating throughout Iraq. Operation Phantom Thunder was a corps level operation, including Operation Arrowhead Ripper in Diyala Province, Operation Marne Torch and Operation Commando Eagle in Babil Province, Operation Fardh al-Qanoon in Baghdad, Operation Alljah in Anbar Province, and continuing special forces actions against the Mahdi Army in southern Iraq and against Al-Qaeda leadership throughout the country. The operation was one of the biggest military operations in Iraq since the U.S. invasion in 2003.
