The Yakima Training Center (YTC〔) is a United States Army training center, used for maneuver training, land warrior system testing and live fire area, located in the south central portion of the U.S. state of Washington. It is bounded on the west by Interstate 82, on the south by the city of Yakima, on the north by the city of Ellensburg and Interstate 90, and on the east by the Columbia River. It comprises 327,000 acres (132,332 hectares) of land, most of which consists of shrub-steppe, making it one of the largest areas of shrub-steppe habitat remaining in Washington state. The terrain is undulating and dominated by three east-west parallel ridges, the Saddle Mountains, Manastash Ridge, and Umtanum Ridge anticlines, which are part of the Yakima Fold Belt near the western edge of the Columbia River Plateau. As is common for shrub-steppe, vegetation consists of sagebrush, bitter brush, and bunch grass.〔( globalsecurity.org article on Yakima Training Center )〕〔 The training center is also used by the Japan Ground Self-Defense Force for exercises. Fort Lewis uses the facility for maneuver and live fire training. Vagabond Army Airfield and Selah Airstrip are located on the Yakima Training Center. ==History== From 1942 to 1946 the U.S. Army leased of land in the area for the Yakima Anti-Aircraft Artillery Range. Then in 1951 the Army purchased for the Yakima Firing Center, which would become the modern Yakima Training Center.〔(Seattle Times article from 12-14-2008 )〕 The United States Army identified a need for a large maneuver area in the Pacific Northwest and appointed a board of officers to negotiate with local landowners to lease 160,000 acres in the Yakima area. In 1941, just prior to World War II, military units in the Pacific Northwest began using the Yakima Anti-Aircraft Artillery Range for range firing and small unit tests; and in 1942 the first temporary buildings were constructed on Umptanum Ridge about eight miles northeast of the current cantonment area. During the latter part of 1942 and 1943, another camp was built in the location of the present cantonment area and was named the Yakima Firing Center. The 9th service Command assumed control of the Yakima Firing Center and supported training for numerous Army Reserve and National Guard infantry, artillery, and engineer units through the remainder of World War II. The Army decided to enlarge the Yakima Firing Center because of increasing training requirements and its future potential. In 1951, the Army bought 261,198 acres at a cost of $3.3 million. Throughout the 1950s and 1960s, Yakima Firing Center supported training activities and exercises for Fort Lewis units and the Washington Army National Guard. These exercises ranged up to division level and included major exercises named HILLTOP, APPLEJACK, and COOLY CREST. In 1965 the United States Marine Corps conducted Operation YAKIMA ATTACK, which was a joint air/ground exercise of the type that illustrates the true value of Yakima Firing Center as a maneuver training area. During the Vietnam era, Yakima Firing Center was used almost exclusively for Army Reserve and National Guard training; Fort Lewis had become a training center and no longer housed a division. However, in 1971 the 9th Infantry Division was activated at Fort Lewis, and in 1974 their first divisional exercise, BOLD FIRE, marked the return of the active Army to Yakima Firing Center. User of the Yakima Firing Center continued to grow over the next several years. The single largest exercise ever conducted at Yakima Firing Center occurred in 1976, when 6,000 active, reserve, and National Guard, and sister services converged on the installation for Joint Training Exercise BRAVE SHIELD. Throughout the 1970s and 1980s, the 9th Division and the Washington Army National Guard trained extensively on the installation. They conducted tank gunner, extensive maneuver exercises, and tests. New equipment was frequently tested at Yakima Firing Center because of its rugged, austere conditions. The new equipment provided greater mobility and the new weapons had greater range, so the Army determined that more area was required. In 1987, actions began that resulted in the acquisition of more than 63,000 acres at a cost of $18 million following congressional approval in 1992. During this period, other major changes occurred for Yakima Firing Center. The 9th Infantry Division deactivated at Fort Lewis, and a brigade from the 7th Infantry Division moved in; construction of the Multi-Purpose Range Complex was completed in 1988 and it opened for business in July 1989, and the Yakima Firing Center was re-named the YAKIMA TRAINING CENTER in 1990. The new name more accurately described the mission and capability of the installation. The force structure at Fort Lewis continued to change, and the stationing of 3 Stryker Brigades from the 2nd Infantry Division, 1 Artillery and ADA Brigade and a Battlefield Surveillance Brigade once again increased training levels at Yakima Training Center. Major improvements to the installation increased its capability to support training. Another major range project, the Multi-Purpose Training Range, was completed; 250 miles of high quality road were constructed; a state-of-the-art Wash Rack facility, a new fuel facility, and an expanded Ammunition Supply Point enhanced the expanded maneuver area. Yakima Training Center provides training support for transient units and organizations by sustaining training lands, range complexes, and support facilities in order to enhance readiness. The installation's customers include not only the Joint Base Lewis-McChord and Army National Guard units, but also Special Operations Command, Marine Corps, Air Force, Navy, and Coast Guard units, plus local and federal Law Enforcement and allied forces from Canada and Japan. The 327,000 acre installation provides an ideal environment for military training and enables the Yakima Training Center to continue to grow as the military's premier training destination in the Pacific Northwest.〔(US Army Webpage Yakima Training Center )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Yakima Training Center」の詳細全文を読む スポンサード リンク
