Sigma I-63 war game

Last updated

Sigma I-63 was one of the series of Sigma war games. These were a series of classified high level war games played in the Pentagon during the 1960s to strategize the conduct of the burgeoning Vietnam War. These simulations were designed to replicate then-current conditions in Indochina, with an aim toward predicting future foreign affairs events. They were staffed with high-ranking officials standing in to represent both domestic and foreign characters; stand-ins were chosen for their expertise concerning those they were called upon to represent. The games were supervised by a Control appointed to oversee both sides. The opposing Blue and Red Teams customary in war games were designated the friendly and enemy forces as was usual; however, several smaller teams were sometimes subsumed under Red and Blue Teams. Over the course of the games, the Red Team at times contained the Yellow Team for the People's Republic of China, the Brown Team for the Democratic Republic of Vietnam, the Black Team for the Viet Cong, [1] and Green for the USSR.

Preparation for these simulations was quite extensive. A game staff of as many as 45 people researched and developed the scenarios. The actual play of the war game involved 30 to 35 participants. There are four or five simulations per year, solicited secretively from the State Department, the Central Intelligence Agency, and major military commands. [3]

Sigma I-63 was played in Spring 1963, in the wake of the disastrous Battle of Luang Namtha. In that battle, the Royal Lao Army had run from half its number of communist soldiers in May 1962, and did not stop for 160 kilometers. [4] [5]

Sigma I-63 was held with senior level officials setting policy for the Red and Blue Teams. Working level officials were the actual players. [2] Major participants were members of the incoming Johnson administration; Chairman of the Joint Chiefs of Staff Maxwell Taylor, Deputy Under Secretary for Political Affairs Alexis Johnson, and Under Secretary of Commerce for Economic Affairs George Ball are known players. [6]

Ambassador William H. Sullivan was another participant. His recollection is that Sigma I-63 ended in a fictional 1970 with 500,000 American troops locked in a stalemate in Vietnam, and conscription riots in the United States. [2] According to another account, after the five-day game played out a hypothetical ten year Vietnam War, the North Vietnamese had increased their infiltration into South Vietnam despite the presence of 600,000 U.S. servicemen. U.S. Air Force General Curtis Lemay was infuriated by the game's predicted results. [6]

Despite Sigma I-63's ending, both Secretary of Defense Robert McNamara and Maxwell Taylor predicted that the greatest part of the American mission in Vietnam would be completed by year's end 1965. [6]

Major General Phoumi Nosavan was a military strongman who was prominent in the history of the Kingdom of Laos; at times, he dominated its political life to the point of being a virtual dictator. He was born in Savannakhet, the French Protectorate of Laos, on 27 January 1920. Originally a civil servant in the French colonial administration of Laos, during the last year of World War II he joined the resistance movement against the Japanese occupiers. Exiled from 1946 to early 1949 for his opposition to French return to colonizing Laos, he returned to his native soil to begin a military career in 1950 after the collapse of the anti-French Lao Issara government. By 1955, he was Chief of Staff of the brand-new Royal Lao Army. While in that position, he was largely responsible for appointing senior officers into command positions in the Military Regions of Laos. Following that, in 1957 he was the first Lao officer to be schooled in France at the École de Guerre. While in France, he became acquainted with Central Intelligence Agency operative John F. "Jack" Hasey. Phoumi returned to Laos to become a founding member of the Committee for the Defence of National Interests on 17 June 1958. On 25 December 1959, he took control of the capital of Vientiane and of the nation in a bloodless coup.

Luang Namtha is a district as well as the capital of Luang Namtha Province in northern Laos. The city lies on the Tha River.

The Battle of Luang Namtha, fought between January 1962 and May 1963, was a series of clashes in the Laotian Civil War. It came about as a result of the turmoil following Laotian independence as a result of the First Indochina War with France. The Kingdom of Laos had foreign soldiers on its soil, and a political struggle in progress concerning those outside troops. Following a coup and counter-coup that left General Phoumi Nosavan in charge, the general decided on military action to settle the political issue of interlopers in Laos.

The Battle of Lak Sao, fought between November 1963 and January 1964, was a major engagement of the Laotian Civil War. In November 1963, General Phoumi Nosavan, who held the reins of military power in the Kingdom of Laos, launched a military offensive against North Vietnamese invaders that cut across the northern panhandle of the nation. Although unsupported in this proxy action by his backers in the U.S. Embassy, he went ahead with his plan to push northwards from Nhommarath, then veer eastwards to the Vietnamese border. Phoumi's Central Intelligence Agency (CIA) advisors warned him that the North Vietnamese would retaliate, but he disregarded them.

Operation Momentum was a guerrilla training program during the Laotian Civil War. This Central Intelligence Agency operation raising a guerrilla force of Hmong hill-tribesmen in northeastern Laos was planned by James William Lair and carried out by the Thai Police Aerial Reinforcement Unit. Begun on 17 January 1961, the three-day Auto Defense Choc course graduated a clandestine guerrilla army of 5,000 warriors by 1 May, and of 9,000 by August. It scored its first success the day after the first ADC company graduated, on 21 January 1961, when 20 ADC troopers ambushed and killed 15 Pathet Lao.

Operation Triangle was a military operation of the Laotian Civil War staged from 19—29 July 1964. Although planned by the General Staff of the Royal Lao Army, it was subject to American approval because the RLA depended on the Americans for finances, supplies, and munitions. Operation Triangle was an ambitious undertaking dependent on martial skills unfamiliar to the Lao. It not only called for coordination of infantry, artillery, and tactical air strikes among forces of three different nationalities; as a covert operation, it also had to have plausible deniability.

The Sigma war games were a series of classified high level war games played in the Pentagon during the 1960s to strategize the conduct of the burgeoning Vietnam War. The games were designed to replicate then-current conditions in Indochina, with an aim toward predicting future events in the region. In almost all runs, the outcome was either a communist win, or a stalemate that led to protests in the US.

The Sigma I-65 war game was one of a series of classified high level war games played in The Pentagon during the 1960s to strategize the conduct of the burgeoning Vietnam War. These simulations were designed to replicate then-current conditions in Indochina, with an aim toward predicting future foreign affairs events. They were staffed with high-ranking officials standing in to represent both domestic and foreign characters; stand-ins were chosen for their expertise concerning those they were called upon to represent.

Over the course of the games, the Red Team at times contained the Yellow Team for the People's Republic of China, the Brown Team for the Democratic Republic of Vietnam, the Black Team for the Viet Cong, and Green for the USSR.

The Sigma I-66 war game was one of a series of classified high level war games played in The Pentagon during the 1960s to strategize the conduct of the burgeoning Vietnam War. Sigma I-66 was based on the unrealistic scenario of a famine-stricken and militarily diminished North Vietnam agreeing to de-escalate its war efforts. It ended with a hypothetical force of 100,000 Viet Cong still in South Vietnam.

The Sigma I-62 war game, played in February 1962, was the first of a series of classified high level war games played in the Pentagon during the 1960s to strategize the conduct of the burgeoning Vietnam War. These simulations were designed to replicate then-current conditions in Indochina, with an aim toward predicting future foreign affairs events. The conclusion drawn from Sigma I-62 was that American intervention in Vietnam would be unsuccessful.

The Sigma I-64 war game, one of the Sigma war games, was played from 6 to 9 April 1964. Its purpose was to test scenarios of escalation of warfare in Vietnam. After rigorous research into information needed to form a scenario, a simulation took place, with knowledgeable officials playing out the roles of actual government decision makers. Participants were drawn from the State Department, Department of Defense, the Central Intelligence Agency, and the Joint Chiefs of Staff. In Sigma I-64, the scenarios to be examined were the burgeoning Viet Cong insurgency in Vietnam, and the possible use of U.S. air power against it.

Operation Hardnose was a Central Intelligence Agency-run espionage operation spying upon the Ho Chi Minh trail that began during the Laotian Civil War. Started in Summer 1963, it soon attracted the attention of the U.S. Secretary of Defense, Robert McNamara. By December 1963, he was calling for its expansion. Operation Hardnose expanded and continued to report on the Ho Chi Minh trail even as American military intelligence activities mounted against the communist supply artery. In an attempt to adapt technology for use by illiterate Lao Theung, some of the U.S. Air Force's survival radios were modified by the CIA for use by their spies.

Team Sone Pet

Team Sone Pet was the code name for a spying foray directed against the People's Republic of China in 1967 and 1968. This classified military operation in the Kingdom of Laos during the Laotian Civil War was an infiltration of spies into Yunnan Province of the People's Republic of China. The operation was run jointly by Lao General Ouane Rattikone and the Republic of China, using an espionage team recruited by the American Central Intelligence Agency. The first mission in 1967 was successful; however, the second mission in 1968 disappeared.

The Royal Lao Army Airborne was composed of the élite paratrooper battalions of the Royal Lao Army (RLA), the Land Component of the Royal Lao Armed Forces, which operated during the First Indochina War and the Laotian Civil War from 1948 to 1975.

Operation Snake Eyes was a proposed military operation of the Laotian Civil War. Planned in mid-December 1969 by the U.S. Ambassador to Laos, the planned interdiction of the newly constructed Chinese Road, Route 46, was aimed at halting the road's progress toward the border with Thailand. The offensive by guerrilla raiders was delayed six months for operational reasons. When it was finally ready to be launched, it was pre-empted by the furor caused by the Cambodian Incursion. Fearful that Operation Snake Eyes would arouse even greater publicity, the Central Intelligence Agency handlers of the guerrillas canceled the operation on orders of the White House. Attempts to limit Chinese expansion toward the south would be left to future operations, such as Operation Phalat and Operation Sourisak Montry.

The Chinese Road were a series of highways built as a foreign aid project by the People's Republic of China (PRC) in northern Laos, beginning in 1962. The first new road was built from Mengla, Yunnan Province, PRC to Phongsali, Laos; it was completed on 25 May 1963. The next major road built was Route 46, begun in the 1966 dry season and stretching from the southern tip of Yunnan Province southward toward the border of the Kingdom of Thailand. As 25,000 Chinese troops and 400 antiaircraft guns came to be posted to defend Route 46, and Thai support of American war efforts in both the Laotian Civil War and the Vietnam War became widely known, there was uneasiness among both Thai and American intelligence communities concerning Communist China's intents in constructing the all-weather highway. American interest in the new road extended up to the White House.
