Prepared by the Afghan Study Team of the Combat Studies Institure, U.S. Army, From the foreword by Genral (ret.) David Petraeus: "In 2010, as the scale and tempo of Coalition operations in Afghanistan increased, so did the need for historical accounts of small-unit actions. As commander of the International Security Assistance Force (ISAF), I commissioned the Combat Studies Institute to research and write the cases collected in this volume and in those that will follow. By capturing key insights from both lethal and non-lethal operations, I hoped these accounts would be of immediate utility to sergeants and lieutenants at the center of future operations. 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 actions leaders of today and tomorrow. The US Army always has prided itself as an institution of constant learning, strongly committed to drawing lessons from its past. This volume from the Combat Studies Institute is an excellent example of that long and honorable tradition. I hope that you will find the actions n Vanguard of Valor to be both instructive and compelling. I am sure that you will find them to be inspirational.
