Staff Sgt. George Thompson marks a steel beam with chalk so it can be cut to its proper length May 1 near Campo, Calif. The beams will be used to finish off an "eyebrow" to a firing range that will allow Border Patrol officers to hone in their weapons skills. Sergeant Thompson is an engineering assistant for the 201st RED HORSE Squadron from Fort Indiantown Gap, Pa. (Photo by Capt. Jay Ostrich)
