The history of the Arkansas Army National Guard and the Global War on Terrorism begins with the expanded use of the National Guard for overseas duties as the United States reduced the size of the active army in an attempt to realize a "Peace Dividend" at the close of the "Cold War". Beginning in the 1990s Arkansas National Guard unit's experience increased Operations Temp and overseas training opportunities. In the late 1990s Arkansas National Guard units began deploying as part of peace keeping operations in the Balkans and in support of ongoing operations in Kuwait and Saudi Arabia. Following the terrorist attacks of 11 September 2001, the National Guard became deeply involved in the Global War on Terrorism, with units deploying to guard infrastructure such as Arkansas Nuclear One and airports as part of Operation Noble Eagle. The Guard initially replaced regular army units on missions such as Middle East peace keeping in order to free these units for combat operations. With the 2003 Invasion of Iraq, the Arkansas National Guard began deploying for combat operations in support of Operation Iraqi Freedom and Operation Enduring Freedom in Afghanistan.
