Foreign Policy is pleased to present this unique and remarkable collection of photographs, largely taken on iPhones (using an app called Hipstamatic that allows users to digitally manipulate "lenses," "flashes," and "film"), of the lives of U.S. Marines in Helmand province in 2010 and 2011 and of the Afghans they interacted with. It is by no means a comprehensive look at 10 years of war, but rather an evocative and profound slice of life -- at the beginning of the end of the longest conflict in U.S. history. This is part three of a five-part series.
