Establishment and growth

Admiral Harry D. Felt, Commander-in-Chief, Pacific, established the U.S. Military Assistance Command, Vietnam, on 8 February 1962, as a subordinate unified command under his control. Lieutenant General Paul D. Harkins, the Deputy Commander in Chief, U.S. Army, Pacific, who, as the commander-designate for the task force headquarters (HQ) in the event of operations in Southeast Asia, had participated in the planning for such operations, was appointed commander and promoted to general. Harkins became the senior U.S. military commander in South Vietnam and responsible for U.S. military policy, operations and assistance there. Harkins had the task of advising the South Vietnamese government on security, organization, and employment of their military and paramilitary forces. As provided for in the organization of the task force headquarters in the contingency plans, MACV's commander was also his own Army component commander. With an initial authorized strength of 216 men (113 Army), MACV was envisaged as a temporary HQ that would be withdrawn once the

for administrative and logistical support, and made its commanding officer the deputy Army component commander under MACV. All U.S. Army units in South Vietnam, excluding advisory attachments, were assigned to the Army Support Group for administrative and logistical needs. Over the course of 1962 U.S. military strength in South Vietnam rose from about 1,000 to over 11,000 personnel. Each service continued to provide its own logistical support. Throughout 1963 the duties of the U.S. Army Support Group steadily increased, particularly regarding to combat support activities and logistics. During the year, the U.S. buildup continued, especially in aviation, communications, intelligence, special warfare and logistic units, reaching a total of 17,068 men, of which 10,916 were Army. Because of this expansion, the commanding general, General Joseph Warren Stilwell Jr. late in 1963 proposed that the name of the support group be changed to U.S. Army Support Command, Vietnam. Harkins concurred and General

With the elapse of five months, all the three same brigades remained in the new division, but the brigade at Chu Lai was now named the 3rd Brigade, 4th Infantry Division, after a responsibility swap that had occurred in August. In April 1966, all Army communications-electronics resources in South Vietnam were combined in a single formation, the 1st Signal Brigade. It supported the combat signal battalions of the divisions and field forces in each corps area. The 1st Signal Brigade operated the many elements of the Defense Communications System in South Vietnam. To improve co-ordination and management of communications-electronics assets, the brigade commander served as the U.S. Army, Vietnam, staff adviser on all matters pertaining to Army communications-electronics. On 24 January 1968, General Westmoreland "cabled to Admiral Sharp a recommendation that the Commander in Chief, Pacific (CINCPAC), and MACV begin contingency planning for the use of tactical nuclear weapons in northern Quang Tri if necessary to prevent a major defeat. He noted that in the uninhabited mountains around Khe Sanh, such weapons could be used with great effect and with “negligible” civilian casualties. Sharp on the thirtieth accepted Westmoreland’s proposal and ordered planners from MACV and CINCPAC’s component commands to meet on Okinawa on 1 February. Assigning the project the code-name Fracture Jaw, Sharp told all concerned to “bear in mind the very sensitive nature” of the planning and to restrict knowledge of it to as few people as possible on an “absolutely essential need to know basis.” Planning began in January 1968 to move nuclear weapons into

so that they could be used on short notice against North Vietnamese troops. However planning quickly ceased after the effort became public in the United States in February.


Naval Forces, Vietnam

In contrast to the carrier, amphibious, and naval gunfire support forces and, at least during early 1965, the coastal patrol force, which Commander Seventh Fleet directed, the Navy's forces within South Vietnam were operationally controlled by COMUSMACV. Initially, Westmoreland exercised this command through the Chief, Naval Advisory Group. However, the increasing demands of the war required a distinct operational rather than an advisory headquarters for naval units. As a result, on 1 April 1966,

As the U.S. military presence in South Vietnam grew, MACV quickly outgrew the Pasteur Street quarters and expanded into a proliferating number of buildings throughout downtown Saigon.

In March 1965, Westmoreland began a search for a new location large enough to accommodate the entire headquarters. He initially tried to obtain a site between the ARVN

The air-conditioned complex of two-story prefabricated buildings, a little more than a third the size of its Washington namesake, included twelve acres of enclosed office space. In addition to the headquarters offices, the complex included a barracks, a mess hall, a refrigerated storage building and its own power plant and telephone exchange. Inside, according to one staff officer, "the well-waxed corridors had the fluorescent feel of an airport terminal." A cyclone fence, topped with barbed wire and with watch towers at intervals, provided close-in protection. Following the closure of MACV and the establishment of the DAO, the MACV Headquarters became the DAO Compound.
