Book excerpt: [Includes 11 illustrations and 6 maps] The Guerilla Warfare in the jungles and paddies of Vietnam was unlike the previous wars that the United States had been involved in for the past hundred years; there were no frontlines, no rest areas, few uniformed enemies and a terrorized population unwilling to help. The tactics, strategies and experiences that would show the way forward were often developed by the small units; squads, platoons and outposts who saw the most of the hard fighting in isolated engagements with their elusive enemies. To ensure that this valuable resource of knowledge and experience was disseminated to all the men of the Corps, the Marine Intelligence department plucked Captain Francis J West Jr and sent him to join the 5th Marines on their day-to-day engagements, patrols and ambushes. What he learnt and recorded, frequently under fire, were the actual experiences of the USMC at the sharp end of the fighting during the Summer of 1966. Aimed at the men of the Corps he wrote of the tense ambushes, long range patrols, 15 second engagements, artillery support, airstrikes and even battalion level sweeps through the awful conditions of the war. A vivid and visceral account of the struggle of the U.S. Marines during the summer of 1966.
