Book excerpt: Fully illustrated throughout with maps, charts, tables and photographs, this authoritative history of the U.S. Army Special Forces during the Vietnam War was written by Colonel Francis Kelly, who himself commanded the 1st and 5th Special Forces Groups during the conflict. From their humble beginnings training just 58 Vietnamese soldiers in 1957, these elite soldiers in just over one decade, trained and advised over 80,000 paramilitary and guerrilla troops in sustained combat techniques, and fought alongside them against the Viet Cong. This is the definitive history of these tough, resourceful and dedicated men.
