EGLIN AIR FORCE BASE, Fla. -- An Air Force F-16C Fighting Falcon from the 78th Fighter Squadron, Shaw Air Force Base, S.C., releases a GBU-31 1,000 pound Joint Direct Attack Munition over Eglin's land range during a test mission in 2003. The 308th Armament Systems Wing works on new and modified munitions to get them through testing and eventually fielded to the warfighter. (Air Force photo /Tech. Sgt. Michael Ammons)
