Exclusive documentary assembled from recently released raw archival footage. Excellent color. Operation Double Eagle in late January, 1966 was the largest Marine amphibious assault since the Korean War and the largest conducted during the Vietnam War. 5,000 marines from 1st Marines, 2nd Battalion, 3rd Marines, 2nd Battalion, 4th Marines, and 2nd Battalion, 9th Marines landed by ship and helicopter in southern Quang Ngai Province near Duc Pho. Great quality color footage shows 20th Squadron "Jolly Green Giant" CH-3C helos operating out of Danang supporting the amphibious landing in a variety of roles including ferrying 105mm howitzers from "Red Beach" inland to forward fire bases, transporting causalities and captured VC, bringing in spare parts and ferrying civilians from the combat zone to safe havens.
