In the first acknowledged combat employment of the fighter jets by the U.S. military, two U.S. Air Force F-35A joint strike fighters conducted air bombardments in the same area on April 30.
The Combined Joint Task Force – Operation Inherent Resolve supported an Iraqi Counter-Terrorism Service attack on ISIS sleeper cells and its support base in the Wadi Ashai area of northern Iraq on April 24.
