Book excerpt: "The purpose of this book is to share Army special operations soldier stories with the general American public to show them what various elements accomplished during the war to drive the Taliban from power and to destroy al-Qaeda and Taliban strongholds in Afghanistan as part of the global war on terrorism. The purpose of the book is not to resolve Army special operations doctrinal issues, to clarify or update military definitions, or to be the 'definitive' history of the continuing unconventional war in Afghanistan. The purpose is to demonstrate how the war to drive the Taliban from power, help the Afghan people, and assist the Afghan Interim Authority (AIA) rebuild the country afterward was successfully accomplished by majors, captains, warrant officers, and sergeants on tactical teams and aircrews at the lowest levels ... This historical project is not intended to be the definitive study of the war in Afghanistan. It is a 'snapshot' of the war from 11 September 2001 until the middle of May 2002"--Page xv.
