not directly used in combat operations. However, in January 1991, three 9th Bombardment Squadron crews deployed to Diego Garcia to join crews from Loring AFB, Fairchild AFB, Castle AFB, and Griffis AFB, to comprise the 4300th Provisional Bomb Wing. Equipped with B-52Gs, the squadron was used in Operation Desert Shield as well as in Operation Desert Storm. The 9th Bombardment Squadron transferred its B-52H's to the 2d Bombardment Wing at Barksdale Air Force Base, Louisiana during 1992, and the squadron was inactivated in August with the end of the Cold War and transfer of Carswell to the U.S. Navy as Naval Air Station Joint Reserve Base Fort Worth (Carswell Field). Reformation from 1993 Equipped with the Rockwell B-1B Lancer, the 9th Bomb Squadron was reactivated on 1 October 1993 at Dyess Air Force Base, Texas. It assumed responsibility for all B-1B initial qualification and instructor upgrade training for Air Combat Command. Since 2000, it has provided bombing, airlift support, training and combat support to combatant commanders. Aircrew have flown conventional warfare taskings since 1993, when the 9th Bomb Squadron starting flying the B-1B. The unit flew more than 300 combat sorties during its four-month deployment in mid-2006 in support of the Global War on Terrorism. During the military intervention against ISIL/Operation Inherent Resolve after 2011, the 9th Bomb Squadron played a pivotal role in the Battle of Kobanî. B-1 bombers were used in the battle. Hundreds of bombs were dropped throughout the course of the battle, and well over 1,000 ISIL fighters were killed. These airstrikes halted ISIL's progress in the city, and may well have been the reason why ISIL lost the battle. After the battle was won, the squadron continued its air campaign in Syria, and contributed to many other ISIL defeats in the north of the region. Since the Battle of Kobanî, Kurdish fighters in the People's Protection Units, alongside allied Free Syrian Army fighters, recaptured over 500 towns and villages from ISIL, as well as the strategic towns of Suluk, Tall Abyad, and Ayn Issa, helped by air support from the squadron.
