The Vietnam War s most highly classified special operations were performed by the Studies and Operations Group. Consisting primarily of U.S. Army Special Forces Green Berets, SOG warriors fought top secret missions deep behind enemy lines. Infiltrate deep into Laos with your Green Beret and Montagnard teammates, hunted by trackers and bloodhounds, outnumbered at times 100-to-1. Rescue downed pilots, ambush convoys, seize enemy prisoners, discover targets for air attacks, and direct air strikes. See why SOG veterans went on to found Delta Force and in the work of secret operations, remain stuff of legends.
