Code-named the Studies and Observations Group, SOG was the most secret elite U.S. military unit to serve in the Vietnam War-its very existence 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.
John L. Plaster, a three-tour SOG veteran, shares the gripping account of SOG's stunning operations behind enemy lines-penetrating heavily- defended North Vietnamese military facilities, holding off mass enemy attacks, and 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.

SOG was a secret operations force in Vietnam, the forerunner of today's Delta Force and Navy SEALs. Exceptionally skilled Green Berets, they were the most highly decorated unit in the war. Always outnumbered-often by as much as 100 to 1-SOG commandos matched wits in the most dangerous environments with an unrelenting foe that hunted them with trackers and dogs. Ten entire teams disappeared and another fourteen were annihilated.
In "Secret Commandos," John Plaster tells of his own remarkable covert activities in SOG from 1969 to 1971, as well as those of dozens of his comrades, vividly describing these unique warriors who gave everything fighting for their country-and for each other.
