Sigma I-64 war game

Last updated

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.

The conclusion drawn from the game was that American air power would have little effect on the Viet Cong because they needed only 15 tons of supplies daily to survive and fight.

Overview

The Sigma I-64 war game was one of a series of classified high level war games played in the Pentagon during the 1960s, codenamed Sigma, to strategize concerning the conduct of the burgeoning Vietnam War. All of these games were designed to replicate conditions in Indochina, with an aim toward predicting future foreign affairs events. 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. [1] [2]

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 usually four or five simulations per year, with the ideas for scenarios solicited surreptitiously from the State Department, the Central Intelligence Agency, and major military commands. [3]

Background

Sigma I-64 was played between 6 and 9 April 1964. [4] It was designed to test secretive scenarios of escalation of warfare in Vietnam, including a gradually increasing bombing campaign. [5] The concept of a massive Chinese intervention like in the Korean War was a major consideration to be explored. [6]

Set up

The exercise was staffed by the State Department, Department of Defense, the Central Intelligence Agency, and the Joint Chiefs of Staff. [1] Although working-level government officers played the actual simulation, cabinet-level senior advisors reviewed the resulting policy conclusions. [2]

Participants

Participants were 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. [1]

The Blue Team in Sigma I-64 represented both the United States and South Vietnam. Its players included:

The Red Team represented the communist nations of the People's Republic of China, the Democratic Republic of Vietnam, the Viet Cong, and the Pathet Lao. Participants for the Red Team are unknown. [1] 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. [2]

Simulation

The projected start date for the game was 15 June 1964. The hypothetical triggering incident was a U.S. flier being shot down and captured, exposing America's role in the stealthily escalating war. Deputy United States Secretary of State Seymour Weiss critiqued the war game thus: "The eventual capture of a US airman is a high probability and would give 'hard' evidence of US involvement". [1] Coincidentally, in reality it turned out that U.S. Navy pilot Charles Frederick Klusmann was actually shot down over the Kingdom of Laos on 6 June 1964 to become the first American aviator downed. [7]

A summary of the war game results noted that intervention in Vietnam would "lay a basis" for similar actions against Cuba. Because the Viet Cong insurgency was within the internationally acceptable limits of covert warfare, an open war waged against them would become an actual war. As a response, the Soviet Union and the People's Republic of China could be expected to change their methods of Cold War opposition to the United States. Adverse public opinion both domestic and foreign would plague the U.S. as a result. [1]

One conclusion to be drawn was that air power would have little effect on North Vietnam's ability to wage war. [8] It was concluded that the North Vietnamese had to ship only 15 tons per day of military supplies to the Viet Cong to maintain the southern insurrection. [9] Even more dismaying, despite a commitment of a projected 500,000 American troops to fighting in Vietnam, the communists were deemed to have won. [10] Prominent military historian H. R. McMaster terms the results as "eerily prophetic". [11]

Results

In Sigma I-64's wake, Robert McNamara disregarded the war game results in favor of an analytically statistical approach. [12] Walter Rostow argued that American air power need not destroy the North Vietnamese ability to support an insurrection in South Vietnam, but only discourage that support. A follow-up war game, Sigma II-64, was scheduled to test his theory. [13]

The Gulf of Tonkin incident was an international confrontation that led to the United States engaging more directly in the Vietnam War. It consisted of a confrontation on August 2, 1964, when United States forces were carrying out covert amphibious operations close to North Vietnamese territorial waters, which triggered a response from North Vietnamese forces. The United States government falsely claimed that a second incident occurred on August 4, 1964, between North Vietnamese and United States ships in the waters of the Gulf of Tonkin. Originally, US military claims blamed North Vietnam for the confrontation and the ostensible, but in fact imaginary, incident on August 4. Later investigation revealed that the second attack never happened. The official American claim is that it was based mostly on erroneously interpreted communications intercepts. The National Security Agency, an agency of the US Defense Department, had deliberately skewed intelligence to create the impression that an attack had been carried out.

<span class="mw-page-title-main">Military simulation</span> Type of simulation

Military simulations, also known informally as war games, are simulations in which theories of warfare can be tested and refined without the need for actual hostilities. Military simulations are seen as a useful way to develop tactical, strategical and doctrinal solutions, but critics argue that the conclusions drawn from such models are inherently flawed, due to the approximate nature of the models used. Many professional analysts object to the term wargames as this is generally taken to be referring to the civilian hobby, thus the preference for the term simulation.

<span class="mw-page-title-main">Taylor-Rostow Report</span>

The Taylor-Rostow Report was a report prepared in November 1961 on the situation in Vietnam in relation to Vietcong operations in South Vietnam. The report was written by General Maxwell Taylor, military representative to President John F. Kennedy, and Deputy National Security Advisor W.W. Rostow. Kennedy sent Taylor and Rostow to Vietnam in October 1961 to assess the deterioration of South Vietnam’s military position and the government's morale. The report called for improved training of Army of the Republic of Vietnam (ARVN) troops, an infusion of American personnel into the South Vietnamese government and army, greater use of helicopters in counterinsurgency missions against North Vietnamese communists, consideration of bombing the North, and the commitment of 6,000-8,000 U.S. combat troops to Vietnam, albeit initially in a logistical role. The document was significant in that it seriously escalated the Kennedy Administration's commitment to Vietnam. It was also seen historically as having misdiagnosed the root of the Vietnam conflict as primarily a military rather than a political problem.

<span class="mw-page-title-main">Joint warfare in South Vietnam, 1963–1969</span> Part of the Vietnam War

During the Cold War in the 1960s, the United States and South Vietnam began a period of gradual escalation and direct intervention referred to as the "Americanization" of joint warfare in South Vietnam during the Vietnam War. At the start of the decade, United States aid to South Vietnam consisted largely of supplies with approximately 900 military observers and trainers. After the assassination of both Ngo Dinh Diem and John F. Kennedy close to the end of 1963 and Gulf of Tonkin incident in 1964 and amid continuing political instability in the South, the Lyndon Johnson Administration made a policy commitment to safeguard the South Vietnamese regime directly. The American military forces and other anti-communist SEATO countries increased their support, sending large scale combat forces into South Vietnam; at its height in 1969, slightly more than 400,000 American troops were deployed. The People's Army of Vietnam and the allied Viet Cong fought back, keeping to countryside strongholds while the anti-communist allied forces tended to control the cities. The most notable conflict of this era was the 1968 Tet Offensive, a widespread campaign by the communist forces to attack across all of South Vietnam; while the offensive was largely repelled, it was a strategic success in seeding doubt as to the long-term viability of the South Vietnamese state. This phase of the war lasted until the election of Richard Nixon and the change of U.S. policy to Vietnamization, or ending the direct involvement and phased withdrawal of U.S. combat troops and giving the main combat role back to the South Vietnamese military.

National Security Action Memorandum Number 263 (NSAM-263) was a national security directive approved on 11 October 1963 by United States President John F. Kennedy. The NSAM approved recommendations by Secretary of Defense Robert McNamara and Chairman of the Joint Chiefs of Staff General Maxwell Taylor. McNamara and Taylor's recommendations included an appraisal that "great progress" was being made in the Vietnam War against Viet Cong insurgents, that 1,000 military personnel could be withdrawn from South Vietnam by the end of 1963, and that a "major part of the U.S. military task can be completed by the end of 1965." The U.S. at this time had more than 16,000 military personnel in South Vietnam.

A wargame, generally, is a type of strategy game which realistically simulates warfare. A professional wargame, specifically, is a wargame that is used by military organizations to train officers in tactical and strategic decision-making, to test new tactics and strategies, or to predict trends in future conflicts. This is in contrast to recreational wargames, which are designed for fun and competition.
