In October 2001 the most militarily advanced nation on earth came into conflict with one of the least developed nations as American forces poured into Afghanistan. The tip of the spear was drawn from the US Special Forces community, and largely from the units of the United States Army Special Forces - the famous Green Berets. Together with the Special Activities Division of the CIA and the Afghan Northern Alliance, they overthrew the Taliban in a lightning campaign that redefined modern warfare.

This new study reveals the grueling Green Beret training and preparation, the specialized equipment they used in the field and traces their deployment throughout the campaign, from the first insertion of forces through to the fall of Kabul and Kandahar, the Taliban uprising at the notorious Fort of War in Mazar-e-Sharif, and the clearance of Tora Bora and Operation Anaconda in the Shahikot Valley.
