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.
