The modern Marine Corps owwes its genesis to the Spanish-American War when the United States entered the world stage. Upon examination of the historical literature of the war, a trove of new writings (and some old) deserved further exploitation. And thus, this anthology.

The author first served with Vietnamese Marines in 1972 when they came on board the U.S. Navy ships that Battalion Landing Team 1/9 was embarked on. They were preparing for an amphibious landing to counter the North Vietnamese Army's Spring Offensive in Military Region 1 (I Corps) in South Vietnam. They brought with them their U.S. Marine advisors who were known by the senior members of the battalion. They had already witnessed or heard of the exploits of then-Captain John Ripley and Lieutenant Colonel Gerry Turley in blunting the initial attacks of the Easter Offensive. As the Vietnamese were formed into helicopter or boat teams and fed a meal before going ashore, they bantered with the American Marines and Sailors, telling them to come along to "kill communists." After a turbulent start to the offensive, the Vietnamese Marines exhibited the fighting spirit that elite units create for themselves. This was reflected in the various names of their battalions that were the focus of their unit identification. The infantry battalions had a series of nicknames and slogans that were reflected on their unit insignia: 1st Battalion's "Wild Bird," 2d Battalion's "Crazy Buffalo," 3d Battalion's "SeaWolf," 4th Battalion's "Killer Shark," 5th Battalion's "Black Dragon," 6th Battalion's "Sacred Bird," 7th Battalion's "Black Tiger," 8th Battalion's "Sea Eagle," and 9th Battalion's "Mighty Tiger." For the artillery units, this was the 1st Battalion's "Lightning Fire," 2d Battalion's "Sacred Arrow," and 3d Battalion's "Sacred Bow." Support and service battalions followed this example as well. The 9th Marine Amphibious Brigade and its embarked troops provided helicopters, amphibious tractors, and landing craft support for a series of attacks leading to the recapture of Quang Tri City through the fall of 1972. In addition, command and control facilities and liaison were provided to the Republic of Vietnam's I Corps and Military Advisory Command Vietnam's 1st Regional Advisory Command in the sustained counteroffensive. This reinforced the impression made by the Vietnamese Marines themselves. This began the interest in the story that follows. The period after World War II saw a number of associated Marine Corps formed in the republics of China, Korea, Vietnam, the Philippines, Indonesia, and Thailand. They had been founded, with the help of foreign military aid, to fight the various conflicts to contain communist expansion in the region. Also present at various times were other Marines from the Netherlands, France, and Great Britain. The beginnings of the Cold War witnessed this proliferation of amphibious forces in Asia, in part because of the reputation the U.S. Marines had earned in the cross Pacific drive against Japan and in other postwar confrontations. This is about one of them, the Vietnamese Marine Corps or Thuy Quan Luc Chien (TQLC). This occasional paper provides documents on the topics of the Vietnamese Marines and the U.S. Marine Advisory Unit from this period.

The History Division has undertaken the publication of various studies, theses, compilations, bibliographies, monographs, and memoirs, as well as proceedings at selected workshops, seminars, symposia, and similar colloquia, which it considers to be of significant value for audiences interested in Marine Corps history. These "Occasional Papers," which are chosen for their intrinsic worth, must reflect structured research, present a contribution to historical knowledge not readily available in published sources, and reflect original content on the part of the author, compiler, or editor. It is the intent of the division that these occasional papers be distributed to select institutions such as service schools, official Department of Defense historical agencies, and directly concerned Marine Corps organizations, so the information contained therein will be available for study and exploitation.

This volume presents a collection of 47 articles describing different aspects of U.S. Marine Corps participation in Operation Iraqi Freedom during 2003. As with the previously published anthologies on the Spanish American, Vietnam, and Persian Gulf Wars, our intent is to provide a general overview that will serve as an interim resource for educating Marines and informing the public about the conflict, until the History Division completes an intended series of monographs dealing with major Marine Corps operations in that campaign. As the operational environment continues to mature, the authors' varied accounts will also serve as an introduction to changing tactics and strategies encountered or developed by Marines conducting stability and support operations in Iraq. Subsequent volumes will cover other campaigns being conducted elsewhere during the Global War on Terrorism.
