Soldiers assigned to 10th Mountain Division rehearse crew drills at Slagle training area, Fort Polk, Louisiana, in June before firing a M982A1 Excalibur precision munition from a M777 howitzer. The new, 70-km range projectile tested on Yuma Proving Ground is quite similar to the one currently in use. (Photo by Staff Sgt. Ashley M. Morris, 3rd Brigade Combat Team, 10th Mountain Division)
