U.S. Soldiers, part of a security forces team assigned to Provincial Reconstruction Team Zabul, sit on the highest part of ?The Castle" and discuss different vantage points May 31, 2010, in Qalat City, Afghanistan. Soldiers hope to use the stone structure, towering over the more than 10,000 inhabitants of Qalat City, to help the PRT fulfill its three goals - improve security, extend the authority and credibility of the Afghan government and facilitate reconstruction.
