Sigma I-62 war game

Last updated

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. [1] 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. [2]

Sigma I-62 background

The United States gradually sank into its role in Indochina as the French departed. Having assumed the French responsibilities in the region, the U.S. found itself facing a volatile future there. In October 1961, President John F. Kennedy was presented with two potential courses of action in Vietnam. His staff members, Walter Rostow and retired General Maxwell Taylor recommended an increase in military advisers and a commitment of 8,000 U.S. combat troops to South Vietnam. A conflicting recommendation by Secretary of Defense Robert McNamara and the Joint Chiefs of Staff called for committing six American combat divisions, comprising 200,000 soldiers. Kennedy held a decision on combat troops in abeyance, [3] though he forwarded 1,000 added advisers to South Vietnam, [4] including Farm Gate instructors from the Special Air Warfare Center at Eglin Air Force Base. [5]

In Southeast Asia, war was already brewing, as President Dwight D. Eisenhower told incoming President Kennedy at his inauguration. The fear was that Southeast Asian nations could fall into communist hands like dominos. [6] In Laos, the ongoing course of events had already led to the start of the Second Indochina War. Troops of the Royal Lao Government were engaged in a slow motion battle at the Luang Namtha near the Chinese border as 1961 turned into 1962. [7]

Sigma I-62 game play

In February 1962, some members of the Joint Chiefs of Staff secretly war-gamed the unfolding situation in Southeast Asia. American interests were represented by the Blue Team, communist adherents by the Red Team. 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 Sigma I-62, the Red Team at times contained the Yellow Team for China, the Brown Team for the Democratic Republic of Vietnam, the Black Team for the Viet Cong, [8] and Green for the USSR. [9]

Preparation for war game 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. 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 game was supervised by a Control appointed to oversee both sides. As the Control Team, McGeorge Bundy and Maxwell Taylor umpired. [10]

From the beginning, Blue Team admitted that because of the communist head start in hidden guerrilla warfare, civic action programs were curbed. The war game director noted, "...it appears that Red wanted to win without a war while Blue wanted not to lose also without a war." [11] The conclusion drawn from Sigma I-62 was that American intervention in Vietnam would be unsuccessful. [2]

Sigma I-62 was held over three years before American combat troops were landed in Vietnam, and two and a half years prior to the Tonkin Gulf Incident. [12] It was the first in a series of wargames in the Sigma series run through the 1960s, most of which showed the US losing the war or locked in a stalemate with a deteriorating home front. In later years, results of Sigma war games would be dubbed "eerily prophetic". [13]

The Royal Lao Air Force, best known to the Americans by its English acronym RLAF, was the air force component of the Royal Lao Armed Forces (FAR), the official military of the Royal Lao Government and the Kingdom of Laos during the Laotian Civil War between 1960 and 1975.

Military Assistance Advisory Group (MAAG) is a designation for United States military advisors sent to other countries to assist in the training of conventional armed forces and facilitate military aid. Although numerous MAAGs operated around the world throughout the 1940s–1970s, including in Yugoslavia after 1951, the most famous MAAGs were those active in Southeast Asia before and during the Vietnam War. Typically, the personnel of MAAGs were considered to be technical staff attached to, and enjoying the privileges of, the US diplomatic mission in a country. "The special status of personnel serving in Military Advisory Assistance Groups (MAAG) results from their position as an integral part of the Embassy of the United States where they perform duty." Although the term is not as widespread as it once was, the functions performed by MAAGs continue to be performed by successor organizations attached to embassies, often called United States Military Groups. The term MAAG may still occasionally be used for such organizations helping promote military partnerships with several Latin American countries such as Peru and the Dominican Republic as well as in African countries such as Liberia.

The Royal Lao Armed Forces, best known by its French acronym FAR, were the official armed defense forces of the Kingdom of Laos, a state that existed from 1949 to 1975 in what is now the Lao People's Democratic Republic. First created under the French protectorate of Laos on July 1, 1949, the FAR was responsible for the defense of the Kingdom since its independence in October 1953 from France, until its dissolution on December 2, 1975. It operated notably during the North Vietnamese invasion of Laos and the Laotian Civil War from 1960 to 1975.

The Laotian Civil War was a military conflict that pitted the guerrilla forces of the Marxist-oriented Pathet Lao against the armed and security forces of the Kingdom of Laos, led by the conservative Royal Lao Government, between 1960 and 1975. Main combatants comprised:

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.

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-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.

Project Hotfoot was a secretive military training mission from the United States in support of the Kingdom of Laos. It ran from 22 January 1959 through 19 April 1961. Working in civilian clothing in conjunction with a French military mission, it concentrated on technical training of the Royal Lao Army.

Operation Junction City Jr. was a major Laotian offensive of the Vietnam War; initially aimed at temporary disruption of the Ho Chi Minh Trail, it was extended into an attempt to isolate the major North Vietnamese communist transshipment point at Tchepone from the units it was supposed to supply.

Operation Maeng Da was a Royal Lao Government military offensive aimed at disrupting the crucial communist supply route of the Second Indochina War, the Ho Chi Minh trail. Launched from a rendezvous point near Vang Tai, Laos, on 2 July 1970 as a three-battalion assault on the major People's Army of Vietnam (PAVN) transshipment center at Tchepone, Laos, it ran into stiff resistance from the PAVN 9th Regiment from 11–15 July. An attempt on 16 July to reinforce the Royalist Blue, Black, and Mobile 1 battalions by White Battalion was thwarted by PAVN ground fire and hazardously heavy air traffic over the battlefield. On 17 July, the worst hit Royalist unit, Black Battalion, was airlifted back out of battle. The other two Royalist battalions exfiltrated away from the PAVN troops. In the process, the commander of Mobile 1 was killed; the battalion lost all combat discipline. Both retreating battalions regrouped at the operation's start point. Although ancillary follow-up operations occurred in the vicinity throughout September, the Maeng Da offensive would not resume. However, the Central Intelligence Agency, which had trained and supported the Royalist guerrilla battalions, prepared the Tchepone Operation to follow it.

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.

Unity was the code name for Thailand's covert supply of mercenary soldiers to the Kingdom of Laos during the Laotian Civil War. From 4 July 1964 until March 1973, battalions of Thai volunteers fought Communist insurgents on the Plain of Jars in Military Region 2. As the Hmong L'Armée Clandestine was sapped by ongoing casualties and a limited basis for replacements, Unity battalions replaced them.
