Nicholas Warr grew up in Oregon and attended Brigham Young University and the University of Oregon before enlisting, at the age of twenty, in the United States Marine Corps. Warr was recommended for the Enlisted Commissioning Program by his Drill Instructors in Boot Camp, and subsequently attended OCS at Marine Corps Base, Quantico, Virginia. Warr graduated from OCS and was commissioned in March 1967.

After attending The Basic School and a six-week high-intensity Vietnamese language training course, his first assignment as an infantry officer sent him to Vietnam from November 1967 until December 1968. He served with the 1st Battalion, 5th Marines, 1st Marine Division as a Platoon Commander, Company Executive Officer and Company Commander during some of the toughest fighting in the Vietnam War.

Warr’s unit was awarded the Presidential Unit Citation for participation in Operation “HUE CITY” during the Tet Offensive of 1968, and he was honorably discharged as a first lieutenant in March 1970. His memoir about his experiences as a Platoon Commander during the fighting inside the Citadel Fortress of Hue, Phase Line Green, The Battle for Hue, 1968, was published by Naval Institute Press in hardcover in 1997 and subsequently in paperback in 1999 by Random House.

Phase Line Green was on the Marine Reading List for over ten years, is well read within the Marine Corps, and is often used as a textbook during Marine Corps training for Urban Warfare. In conjunction with several other Marines who fought in Hue, Mr. Warr has developed a white paper, entitled Lessons Learned, Operation HUE CITY which is available to all American military commands and was studied extensively during the operational planning for Operation IRAQI FREEDOM.

Mr. Warr’s 2nd book, Charlie One Five; A Marine Company’s Vietnam War, was published in June, 2013, by Texas Tech University Press. This book includes stories experienced by Mr. Warr in combat, as well as the personal combat histories of over thirty U. S. Marines who served in the 1st Battalion, 5th Marines during the early years of the war. Mr. Warr’s third book, which is under development, will complete a “trilogy” of books that document the combat history of one of the most highly decorated infantry battalions during the Vietnam War. Like his 2nd book, this book focuses on the Marines and sailors serving in Charlie Company, but it also documents many other combat operations and battles involving the other infantry companies of this legendary U. S. Marine infantry battalion.
