This is the companion photo history to SOG: The Secret Wars of American's Commandos in Vietnam. In 1972 the U.S. military took steps to ensure that such a book could never be printed by destroying all the known photos that existed of the top-secret Studies and Observations Group. But unknown to those in charge, SOG veterans brought back with them hundreds of photographs of SOG in action and kept them secret for more than three decades. More than 700 irreplaceable photos bring to life the stories of SOG legends Larry Thorne, Bob Howard, Dick Meadows, George Sisler, "Q" and others, and documents what really happened deep inside enemy territory: Operation Tailwind, the Son Tay raid, SOG's defense of Khe Sanh, Hatchet Force operations, Bright Light rescues, HALO insertions, string extractions, SOG's darkest programs and much more.
