Since 2001, the US Army in Afghanistan has been conducting complex operations in a difficult, often dangerous environment. Living in isolated outposts and working under austere conditions, US Soldiers have carried out missions that require in equal parts a warrior's courage and a diplomat's restraint. In the larger discussions of the Afghanistan campaign, the experiences of these Soldiers - especially the young sergeants and lieutenants that lead small units-often go undocumented. But, as we all know, success in Afghanistan ultimately depends on these small units and their leaders, making their stories all the more important. In 2010, as the scale and tempo of Coalition operations in Afghanistan increased, so did the need for historical accounts of small-unit actions. The eight actions described in these pages take the reader through a wide range of platoon-level operations, from an intense firefight near Kandahar to an intricate civic action project in Kunar Province. Drawing from dozens of Soldier interviews, these accounts vividly depict the actions themselves and offer critical insights of greatest benefit to the small-unit leaders of today and tomorrow.
