"The most comprehensive examination of widespread covert American actions during the Vietnam War."-Kirkus Reviews

Code-named the Studies and Observations Group, SOG was the most secret elite U.S. military unit to serve in the Vietnam War-so secret its very existence was denied by the government. Composed entirely of volunteers from such ace fighting units as the Army Green Berets, Air Force Air Commandos, and Navy SEALs, SOG took on the most dangerous covert assignments, in the deadliest and most forbidding theaters of operation.

Major John L. Plaster, three-tour SOG veteran, shares the gripping exploits of these true American warriors. Here is a minute-by-minute, heartbeat-by-heartbeat account of SOG's stunning operations behind enemy lines-penetrating heavily defended North Vietnamese military facilities, holding off mass enemy attacks, launching daring missions to rescue downed U.S. pilots. From sabotage to espionage to hand-to-hand combat, these are some of the most extraordinary true stories of honor and heroism in the history of the U.S. military.
