High quality reprint of this recently declassified 1971 study.The primary mission of Ranch Hand was defoliation and crop destruction. Defoliation was directed against enemy strongholds, roadsides, power lines, railroads, and other lines of communication. The objectives were to increase visibility for Forward Air Controller (FAC) and tactical aircraft and to make it more difficult for the enemy to ambush ground forces. Two herbicides were used for. defoliation: Orange, a mixture of 2,4-D and 2,4,5-T chlorophenoxy acids; and White, a mixture of 2,4-D and picloram. Crop destruction was directed at food plots of enemy troops, the objective being to increase their logistics problem. The herbicide used for crop denial missions was Agent Blue, a sodium salt of cacodylic acid. Proposed targets were carefully screened at all echelons. Requests for defoliation and crop destruction were originated by army commanders at or below the province level. The request, when approved by the Province Chief, was sent to the Vietnamese Joint General Staff (JGS). With their approval, it went to Military Assistance Command, Vietnam (MACV) which reviewed specific target areas and operational requirements. A coordination meeting was then held at the province where the final plan was agreed upon. Following this, an operations order was published by the JGS and an execution order issued by MACV. It required approximately six months from the time the request for defoliation was first submitted until the final plan was agreed upon by all levels of command. A second mission of the Ranch was that of conducting airlift operations as directed by higher authority. This was accomplished by removing the spray tanks and spray booms from the aircraft and installing the conveyors and other essential equipment for airlift operations. The conversion, when required, was accomplished in less than 24 hours.

High quality reprint of this recently declassified 1968 eport. "The War in Vietnam--July - December 1967" summarizes and provides an overall look at the Air Force role in North and South Vietnam for the semi- annual period. It is a continuation of the summary of Air Force operations first detailed in "The War in Vietnam - 1965." ROLLING THUNDER gradually increased the weight of effort against a broadening, but still limited, target complex. The high incidence of radar-directed guns and SA-2s in the extended battle area also required changes in tactics by strike and reconnaissance forces. Close air support was instrumental in breaking the enemy attacks on Dak To, Loc Ninh, and Bo Duc, often by putting ordnance within 20 feet of prepared Allied positions. Airlift units retained their basic organizational structure and successfully supported the Allied requirements at Loc Ninh and Dak To. Flying safety was the paramount problem confronting the Vietnamese Air Force (VNAF), and by August, aircraft losses due to pilot error exceeded combat losses, until finally an intensive instrument training program was initiated. The denial of crops through herbicide destruction often placed a severe strain on the enemy supply system, forcing the North Vietnamese Army (NVA) out of their normal operating areas. Enemy attacks against air bases with a steadily improving rocket capability continued to present formidable problems. Successful efforts were made during the period to substantially increase the B-52 monthly sortie rate to keep pressure on the enemy's supply and infiltration system, while at the same time blocking his efforts to mass along the DMZ.

High quality reprint of this recently declassified 1968 study."The War in Vietnam" provides an overall look at the Southeast Asia situation, as it relates to the role of the United States Air Force. Intensifying its air operations, the USAF increased its close air support, interdiction, fixed-wing, and helicopter support. New tactics were also used to improve the Search and Rescue capability in highly defended areas and measures were devised to minimize limitations of aircraft in recovering downed airmen. In an effort to exhaust enemy resources and remove his sanctuaries in North Vietnam, one of the major objectives of the air campaign was greater targeting freedom. A probing for target alternatives showed destruction of hard-to-replace vehicles could be more effective than "cratering a road, interdicting a rail line, or destroying a bridge." Since enemy strategy emphasized prolonging the war by keeping the U.S. out of the: Hanoi/Haiphong region, CINCPAC enumerated methods of attacking his air defense system, including MIG air bases and aircraft on the ground.

One of the more striking aspects of the war in Southeast Asia was the adaptation of existing weapons in the American arsenal to the peculiar needs of an unconventional war. This volume traces the history from initial conception of the fixed-wing gunship in the early 1960's through deployment and operations to the end of American combat involvement in early 1973.

The Defense Intelligence Agency (DIA) was the first new agency established by Secretary of Defense Robert McNamara after he assumed office in 1961. The ambitious McNamara intended to reformulate U.S. strategic nuclear policy and reduce inefficiencies that had developed in the Department of Defense (DoD) in the 1950s. DIA was the lynchpin to both efforts. In the early and middle 1960s, McNamara and his subordinates, Deputy Secretary of Defense Roswell Gilpatric and new DIA Director Lieutenant General Joseph Carroll (USAF), worked hard to establish the Agency, but their efforts were delayed or stymied by intransigent and parochial military leadership who objected to the creation of DIA because they feared a loss of both battlefield effectiveness and political influence in Washington, D.C.1 The work of building the DIA was made all the more urgent by the deteriorating situation in Southeast Asia. By the early 1960s, millions of dollars and hundreds of advisory personnel sent by the U.S. were having a negligible impact on the anti-communist campaign there. As the U.S. continued to commit more resources to the ill-fated government in Saigon, the country found itself drawn deeper and deeper into the maelstrom. For DIA, the looming war in Southeast Asia would expose major problems in its organization and performance. Especially in the period from 1961 to 1969, DIA, either because of structural weaknesses or leadership failures, often failed to energetically seize opportunities to assert itself in the major intelligence questions involving the conflict there. This tendency was exacerbated by national military leadership's predilection for ignoring or undercutting the Agency's authority. In turn, this opened up DIA to severe criticism by Congress and other national policymakers, some of whom even considered abolishing the Agency. During the war, McNamara's great hope for reforming military intelligence would be swept up in quarrels between powerful domestic adversaries, and DIA's performance left the Secretary of Defense deeply embittered toward his creation. It was only at the end of the war that DIA assumed a more influential role in Southeast Asia. Until then, however, the Agency was consigned to the wilderness when it came to questions about the Vietnam conflict.

A book about the elite Army Ranger of the Republic of Vietnam

Published for the fortieth anniversary of the final days of the Vietnam War, this is the suspenseful and moving tale of how John Riordan, an assistant manager of Citibank's Saigon branch, devised a daring plan to save 106 Vietnamese from the dangers of the Communist takeover.Riordan,who had served in the US Army after the Tet Offensive and had left the military behind for a career in international banking,was not the type to take dramatic action, but once the North Vietnamese Army closed in on Saigon in April 1975 and it was clear that Riordan's Vietnamese colleagues and their families would be stranded in a city teetering on total collapse, he knew he could not leave them behind. Defying the objections of his superiors and going against the official policy of the United States, Riordan went back into Saigon to save them.In fifteen harrowing trips to Saigon's airport, he maneuvered through the bureaucratic shambles, claiming that the Vietnamese were his wife and scores of children. It was a ruse that, at times, veered close to failure, yet against all odds, the improbable plan succeeded. At great risk, the Vietnamese left their lives behind to start anew in the United States, and now John is known to his grateful Vietnamese colleagues and hundreds of their American descendants as Papa. They Are All My Family is a vivid narrative of one man's ingenious strategy which transformed a time of enormous peril into a display of extraordinary courage. Reflecting on those fateful days in this account, John Riordan's modest heroism provides a striking contrast to America's ignominious retreat from the decade of conflict.
