An F-15E Strike Eagle from the 4th Fighter Wing at Seymour Johnson Air Force Base, N.C., drops a Guided Bomb Unit 31 during a Combat Hammer mission over the Eglin Air Force Base Range during the week of March 16. Combat Hammer is also known as a Weapons System Evaluation Program for air-to-ground weapons. The 83rd Fighter Weapons Squadron executes the 'Hammer' missions by evaluating the entire weapons process from loading to flight to the target. Flying squadrons 'deploy' to Eglin for the week-long evaluation. Courtesy photo.
