United States Army Pacific


The United States Army Pacific is an Army Service Component Command which serves as the Army component for United States Indo-Pacific Command. It may also serve as a Joint Task Force headquarters. The command has forces in Alaska, Hawaii, Japan, and South Korea. It also performs missions in Southeast Asia, in the countries stretching from the Philippines all the way to Bangladesh and India.
United States Forces Korea has had operational command and control of U.S. forces in Korea since January 2012, and USARPAC headquarters oversees the manning, training, and equipping of Army forces assigned to USFK.
Subordinate units of this command have performed humanitarian missions in places as widely separated as Haiti, Cuba, and the Middle East.

History

The first U.S. Army formation established in Hawaii was the District of Hawaii, on 25 October 1910. It was succeeded on 1 October 1911, by the Department of Hawaii, and on 15 February 1913, by the Hawaiian Department. Brigadier General Montgomery M. Macomb was the first commander of the Hawaiian Department. Headquartered in the Alexander Young Hotel, it moved to Fort Shafter in 1921. The department also started wearing the red octagon insignia bearing the yellow letter "H." The colors symbolized Hawaiian royalty and the eight sides represented the main islands of Hawaii.
Lieutenant General Walter Short was commanding the Hawaiian Department in early December 1941, when the Japanese attack on Pearl Harbor took place. He was quickly recalled to the mainland. To replace him, Lieutenant General Delos Emmons was returned by General Henry "Hap" Arnold to Hawaii as commanding general of the Department on December 17, 1941, ten days after the attacks. He encouraged the creation of the Hawaii Defense Volunteers. He organized the replacement of the island's U.S. banknotes with new dollars overprinted with the word HAWAII; if the area were occupied, U.S. authorities could declare all marked dollars void and thereby render worthless all money which fell into enemy hands. He also requested Army Air Forces Headquarters to send additional planes and received them as rapidly as possible. Emmons built up the forces in Hawaii, anticipating the Battle of Midway. After Admiral Chester Nimitz became Commander-in-Chief, Pacific Ocean Areas in May 1942, the Hawaiian Department came under his command.
On 26 May 1943, General Robert C. Richardson Jr. arrived in Hawaii as the new commander of the Hawaiian Department. In July, he radically reorganized his command, placing the major air and ground forces in the area under seven major commands—all under his direct control. In recognition of the importance of shipping in an oceanic theater, he abolished the old Service Forces and created instead an Army Port and Service Command. A Hawaiian Artillery Command was also established, and a Department Reserve designated. All the combat divisions in the area, as well as those expected, were placed under separate command and a task force headquarters was formed in anticipation of future needs. Finally, Richardson appointed a deputy chief of staff for operations, who became, in effect, a War Plans officer.
On 14 August, Richardson assumed the title Commanding General, U.S. Army Forces, Central Pacific Area "by direction of the President."
The geographical extent of General Richardson's authority under this directive, as distinguished from his command of the Hawaiian Department, corresponded to the area delineated as the Central Pacific in Nimitz' original directive. It encompassed all the land and sea areas of the Pacific between the equator and the 42nd parallel, to the north, except for that portion of MacArthur's Southwest Pacific Area that lay north of the equator and a small strip off the coast of South America. Within this vast region—of which only a small portion was in American hands—Richardson had responsibility for administration and training of all U.S. Army troops, whether ground or air. This responsibility included also supply, but the precise nature of these duties was left undefined pending his recommendations. General Richardson had no responsibility for operations other than to assist "in the preparation and execution of plans" involving Army forces in the area, "subject to the direction of the Commander-in-Chief, Pacific Ocean Area."
In designating Richardson as Commanding General, U.S. Army Forces, Central Pacific Area, the War Department said nothing about his duties as Hawaiian Department commander. His responsibilities for both were about the same, but the older command—which carried certain additional legal responsibilities—had been established by Congress and could only be altered by that body. Did Richardson still retain those functions unique to the Hawaiian Department or had the new directive superseded the old? This confusion was quickly settled when the War Department on 18 September affirmed the continued existence of the Hawaiian Department under Richardson and stated explicitly what had been left implicit before—that its instructions to Richardson were not intended to affect the status of the Hawaiian Department.
Fort Shafter became a busy headquarters, and the barracks on Palm Circle were converted to offices. The major headquarters received the following names: U.S. Army Forces, Central Pacific Area ; U.S. Army Forces, Pacific Ocean Areas ; and U.S. Army Forces, Middle Pacific. In 1944, the Army Corps of Engineers erected the "Pineapple Pentagon" in just 49 days.
On 1 February 1947, the U.S. Army Forces, Middle Pacific became U.S. Army Pacific.
During the Korean War, USARPAC provided combat forces, training, and logistics. On 1 July 1957, USARPAC became a component of the U.S. Pacific Command.
During the Vietnam War, USARPAC provided similar support to United States Army Vietnam. After the war, the Army cut its presence in the region, since large amounts of combat forces in the Pacific were no longer needed. On 31 December 1974, USARPAC was inactivated. Army forces in Korea and Japan became separate major commands. In Hawaii, USARPAC headquarters was superseded by U.S. Army Support Command Hawaii and a Department of the Army field operating agency—the U.S. Army CINCPAC Support Group.
The Army established United States Army Western Command on 23 March 1979 as a major command. WESTCOM was the Army component of the joint U.S. Pacific Command. The new WESTCOM took command of Army forces in Hawaii. In 1989, WESTCOM added United States Army Alaska from FORSCOM. In 1990, United States Army, Japan transferred under WESTCOM, losing its status as a major Army command.
In August 1990, WESTCOM was redesignated United States Army Pacific.
On 1 October 2000, USARPAC reorganized into an Army service component command.
Since the September 11 attacks, the command has played a major role in the homeland defense of the United States. To fill operational gaps, the command sent soldiers to the War in Afghanistan and the Iraq War.
USARPAC has sent forces on multiple humanitarian missions, disaster relief, and defense support of civil authorities.

Commander's responsibilities

  • Responsible to Secretary of the Army for execution of 10 USC §7013 responsibilities
  • Admins and supports army units assigned or attached to United States Indo-Pacific Command
  • Reports to the Commander, United States Indo-Pacific Command

    Insignia Design

Designed in 1944, USARPAC's insignia reflects the axis of advance across the Central Pacific then underway. A blue disc symbolizes the heavens, with twelve white stars that show Polaris, seven stars of the Big Dipper, and four stars of the distinctive Southern Cross. Polaris's sitting above the horizon indicates the latitude of Hawaii. Cutting across the star field is a red on white Arrow of War, unsupported in the sky, signifying the Armed forces is self-reliant. The colors red, white, and blue are symbolic of our national flag, and decoding the starts reveals a key date - December 7th, 1941.

Organization

Former units include the U.S. Army Chemical Activity, Pacific, at Johnston Atoll, which traced some of its history to the 267th Chemical Company and the Project 112 biological warfare defense experiments. This became the Johnston Atoll Chemical Agent Disposal System, which was finally deactivated in 2001.
