An F-15 Strike Eagle rolls down the runway on takeoff Dec. 11 in Southwest Asia. The F-15s are deployed to the 494th Expeditionary Fighter Squadron in support of Operation Iraqi Freedom. The 494th EFS was the first unit to fly the guided bomb unit 39/B small diameter bomb into combat in October. The new bomb, the first of its kind in the Air Force inventory, gives aircrews the ability to destroy targets that would normally be passed over due to the proximity of friendly troops, civilians, structures or personal property.
