U.S. Army Sgt. Barry Dilley, supply non-commissioned

U.S. Army Sgt. Barry Dilley, supply non-commissioned officer of the Oklahoma Army National Guard's 1st Battalion, 279th Infantry, walks down a path at Combat Out Post Herrera Nov. 28, 2011. The COP, which sits 8,700 feet above sea level and is surrounded by mountains and local villagers, received a Joint Precision Airdrop System resupply Nov. 27, 2011, consisting of 18,000 lbs of fuel. COP Herrera's local terrain, coupled with the high Taliban presence, makes it difficult for ground resupply missions.
