Mine resistant ambush protected military all-terrain vehicles gather at a security collection point to provide over watch support for the 838th Air Expeditionary Advisory Group advisers during a humanitarian site-survey mission directly outside of Shindand Air Base, Afghanistan, March 22, 2012. The advisers’ focus is the rerouting of flood water that is causing damage to various aqueduct systems and repair of a collapsed karez, a water supply system that feeds the villagers, live stock and crops of the Moghalan-e-now and Moghalan-khona villages.
