80-749: The United States Army, Vietnam ( USARV ) was a Corps-level support command of the United States Army during the Vietnam War . Although the U.S. Army Support Group was the Army component command within Military Assistance Command, Vietnam (MACV) in 1962, its functions were limited to logistical and administrative matters and excluded operational matters, which were the concern of the chief of Military Assistance Advisory Group , Vietnam. Neither headquarters could qualify as
160-582: A corps d'armée in 1815 for commanding his mixed allied force of four divisions against Napoleon I. When the British Army was expanded from an expeditionary force in the First World War, corps were created to manage the large numbers of divisions. The British corps in World War I included 23 infantry corps and a few mounted corps. The word was adopted for other special formations such as
240-629: A 1 ⁄ 8 inch (0.32 cm) white border three vertical stripes yellow, blue and red, on the center blue stripe a sword pointing upward, blade white and handle yellow. Yellow and red are the colors of Vietnam. The blue center represents the United States, together with the sword it alludes to the U.S. Military in Vietnam. The shoulder sleeve insignia was approved on 10 February 1966. (TIOH Dwg. No. A-1-408) A gold color metal and enamel device 2 inches (5.1 cm) in height consisting of

This corps was renamed I Canadian Corps as a second corps headquarters was established in the UK, with the eventual formation of five Canadian divisions in England. I Canadian Corps eventually fought in Italy, II Canadian Corps in northwest Europe, and the two were reunited in early 1945. After the formations were disbanded after VE Day, Canada has never subsequently organized
400-457: A MEF headquarters group, a Marine division, a Marine aircraft wing, and a force service support group (re-designated as Marine logistics group in 2005). The pre– World War II Red Army of the former USSR had rifle corps much like in the Western sense with approximately three divisions to a corps. However, after the war started, the recently purged Soviet senior command ( Stavka ) structure
480-518: A communications regiment (or a separate battalion). In 1945, air defence corps could include 1 anti-aircraft artillery brigade or division. Air defence fighters operating within the limits of responsibility of the KPVO was transferred to the corps. By the end of the war, there were 14 KPVO in the Active Army, of which 5 corps continued to carry out the tasks assigned to them even after the war, and

The commanding officer can be a captain (Previously, Commanding Officers of a large corps could have been a Major, but that capability has been removed with the creation of CJCR Group Order 5511-1) The National Revolutionary Army (NRA) corps ( 軍團 ) was a type of military organization used by
640-484: A corps is a battlefield formation composed of two or more divisions , and typically commanded by a lieutenant general . During World War I and World War II , due to the large scale of combat, multiple corps were combined into armies which then formed into army groups . In Western armies with numbered corps, the number is often indicated in Roman numerals (e.g., VII Corps ). The Australian and New Zealand Army Corps
720-407: A corps is also a grouping of personnel by common function, also known as an arm , service , mustering or branch . In the British Army, an administrative corps performs much the same role – for personnel that otherwise lack them – as a ceremonial regiment . An administrative corps therefore has its own cap badge , stable belt , and other insignia and traditions. In some cases, the term corps
800-500: A dedicated Cavalry Corps of three divisions and horse artillery assigned to the corps headquarters. In the early years of the war, field artillery was either part of an artillery reserve under direct army control or assigned to individual divisions. However, after the Battle of Chancellorsville the divisional artillery was placed under corps control, with each corps assigned a brigade of between four and six batteries commanded by

As a result of Engler's appraisal, logistic advisory functions were transferred to USARV headquarters, but the broader question of USARV's status was not resolved. Lieutenant General Bruce Palmer, Jr. , who succeeded Engler on 1 July 1967, elevated the logistic advisory group within the USARV staff to a general staff section, which he designated the Military Assistance Section. This action
1040-606: A logistical command, as envisaged in contingency plans. These developments strengthened the arguments of planners who wanted an Army headquarters to command U.S. Army ground forces. In view of the possible deployment of major Army ground combat forces to South Vietnam, the Army Chief of Staff , General Harold K. Johnson , recommended to the Joint Chiefs of Staff in March 1965 that a separate U.S. Army component command, under

This staff consisted of a chief of cavalry, a chief of artillery, and representatives of the War Department 's various bureaus: an assistant adjutant general , a quartermaster , an assistant inspector general , a commissary of subsistence, an ordnance officer (all with the rank of lieutenant colonel ), and a medical director. However, there were no dedicated combat service support formations as part of

This allowed Napoleon I to mass the bulk of his forces to effect a penetration into a weak section of enemy lines without risking his own communications or flank. This innovation stimulated other European powers to adopt similar military structures. The corps has remained an echelon of French Army organization to the modern day. As fixed military formation already in peace-time it
1280-522: A result of the study, Westmoreland established the post of Assistant Chief of Staff, Military Assistance, in the MACV staff to provide that focus. He also appointed a temporary committee to determine what functions could be transferred between MACV and USARV headquarters. On the committee's recommendation, logistic advisory functions were transferred from USARV, back to MACV in February 1968. USARV controlled

In April 1966 he requested the deployment of a Women's Army Corps (WAC) detachment to support USARV and he finally received approval from the Joint Chiefs of Staff on 25 July 1966 with the first WACs arriving in late October 1966. On 15 June 1967 he was appointed as Deputy Chief of Staff for Logistics. He retired from

This lanyard is a woven piece of cord which is worn on ceremonial uniforms and dates back to the issue of clasp knives in the early 20th century which were secured to the uniform by a length of cord. If a soldier is posted to a unit outside of their parent corps, except in some circumstances the soldier continues to wear
1520-623: A true Army ground component command. In late 1964 and early 1965, when a major buildup of U.S. Army ground combat forces in South Vietnam was imminent, planners from U.S. Army, Pacific and the Department of the Army began to restudy current command arrangements. The ever-growing responsibilities of the Army Support Command, especially its duties as the U.S. Army component headquarters, precluded its reorganization into

A purely national Corps headquarters could be quickly reconstituted if necessary. It took command of the International Security Assistance Force in Afghanistan on 4 May 2006. Previously, it was deployed as the headquarters commanding land forces during

2880-589: The Army and Marines diverged in their approach to the concept of the field corps. The Army continued to group its divisions into traditional corps organizations in the Continental United States (CONUS), West Germany ( V Corps and VII Corps ), and South Korea (I Corps). However, during the Vietnam War , the Army designated its corps-level headquarters in South Vietnam as I Field Force and II Field Force to avoid confusion with
2960-690: The Civil War lacked standing organization at the corps and division levels, it moved swiftly to adopt these during the mobilization for the Spanish–American War in the spring of 1898. On 7 May, General Order 36 called for the establishment of seven "army corps" (repeating the nomenclature of the Civil War); an eighth was authorized later that month. Two of these saw action as a unit: the Fifth in Cuba and
3040-459: The Confederate corps at the Battle of Gettysburg , for instance, exceeded 20,000 men. However, for both armies, unit sizes varied dramatically with attrition throughout the war. In Civil War usages, by both sides, it was common to write out the number, thus "Twenty-first Army Corps", a practice that is usually ignored in modern histories of the war. Although the US Army in the years following

In 1965, all three MEFs were subsequently re-designated as Marine amphibious forces or MAFs, and in 1988 all three Marine Corps corps-level commands were again re-designated as Marine expeditionary forces (MEF). The MEF had evolved into a self-contained, corps-level, Marine air-ground task force (MAGTF) consisting of
3440-535: The MACV commander, General William Westmoreland , both opposed Johnson's recommendation. On the other hand, MACV's Chief of Staff, Major General Richard G. Stilwell , held that an Army component command would prove to be a valuable coordinating link between MACV, the U.S. Army, Pacific and the U.S. Army Support Command. Through July 1965 there was a constant exchange of views between Westmoreland and General John K. Waters , Commander in Chief, U.S. Army, Pacific, concerning

Engler , Deputy Commanding General, USARV, to study whether USARV headquarters should assume the Army's logistical advisory functions, which at the time were being performed by MACV's J-4 section, the Logistics Directorate. After completion of his survey, Engler made several observations and recommendations. The entire Army military assistance and advisory effort should, he contended, be

In June 1967 COMUSMACV approved the replacement of a USARV staff section that had handled civil affairs and civic action with an assistant chief of staff for Civil Operations and Revolutionary Development Support . By mid-1967, USARV, 1st Logistical Command, and many other Army units dispersed in Saigon were moved to Long Binh Post to resolve centralization, security, and troop billeting issues. When General Creighton Abrams succeeded Westmoreland as COMUSMACV in June 1968 he continued Westmoreland's policy of delegating most Army logistical and administrative matters to his deputy commanding generals of USARV, successively Lieutenant Generals Frank T. Mildren and William J. McCaffrey . Abrams claimed late in 1971 that he held onto
3680-443: The Soviet air defence corps were also created. In June–July 1960, all KPVO were enlarged and consisted of: anti-aircraft missile regiments and brigades, air defense fighter regiments, radio engineering regiments and brigades, separate electronic warfare battalions, regiments and battalions of communications and logistics institutions. In many English-speaking countries and other countries influenced by British military traditions,
3760-433: The U.S. Army Support Command be redesignated Deputy Commanding General, USARV; and that all Army units deployed to South Vietnam be assigned to the USARV headquarters. Westmoreland recommended the establishment of several Army corps level headquarters in South Vietnam which, under his operational control, would conduct U.S. combat operations in their respective tactical zones. Westmoreland's proposals were approved by Waters and

He personally reviewed and approved all assignments and reassignments of Army generals in South Vietnam and exercised a strong influence over which generals the Department of the Army sent to his command. In early 1969 in order to support the Vietnamization effort USARV established an advisor school at Dĩ An Base Camp to train U.S. advisors who would be assigned to Mobile Advisory Teams .

Thus he was put in the position of having to serve two masters: the Commander in Chief, Pacific, and the Commander in Chief, U.S. Army, Pacific. Similarly, U.S. Army organizations in South Vietnam were responsible to the head of MACV for combat operations and to the commander in chief of U.S. Army, Pacific, for Army matters. The overlapping chains of command resulted in duplication and confusion within

Initially, corps were numbered in relation to their field army, such as I Army Corps, Army of the Potomac. After a while these numerical designations became unique to each corps regardless of the army to which they were assigned. Although designated with numbers that are sometimes
4400-433: The deputy commander of MACV actually supervised its operations. In early 1967,in order to improve South Vietnamese military morale and reduce desertion rates, COMUSMACV ordered USARV to assume responsibility for improving the South Vietnamese military field ration utilization, for garrison ration commodities and for the distribution system. In addition USARV assigned responsibility for the construction of dependent housing for

Engler concluded that MACV was no longer operating as a military assistance command in the true sense of the term, since U.S. tactical forces had been so greatly increased and their mission expanded. Engler maintained that logistics should not be separated from operations and advisory activities, and therefore these functions should be performed by USARV, in an expanded role as

From December 1948 to January 1949, all anti-aircraft artillery corps were disbanded. In June 1954, for the defense of the main industrial and economic centers and regions of the USSR, 10 air defence corps were re-created. At

In the Confederate States Army , field corps were authorized in November 1862. They were commanded by lieutenant generals, and were usually larger than their Union Army counterparts because their divisions contained more brigades, each of which could contain more regiments. All of
