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.
