The United States Army's [[I Corps (United States)|I Corps]] commands most Army units at Joint Base Lewis-McChord and conducts planning and liaison with other assigned active and Reserve component units in the continental United States. It is one of the active Army's contingency corps. I Corps stays prepared to deploy on short notice worldwide to command up to five divisions or a joint task force.<ref name="Icorps">[http://info.lewis-mcchord.army.mil/corps-history Joint Base Lewis-McChord I Corps history]{{dead link|date=April 2025|bot=medic}}{{cbignore|bot=medic}}</ref>

In 1981, the I Corps was reactivated at Fort Lewis. On October 12, 1999, General [[Eric K. Shinseki]], Chief of Staff of the Army, announced I Corps would lead the acceleration of Army transformation, training, and the initial creation of the first two [[Stryker Brigade Combat Team]]s at Fort Lewis.<ref name="Icorps"/> Since September 11, 2001, I Corps and Fort Lewis assets have been active in providing support for [[Global War on Terrorism]] operations, including [[Operation Noble Eagle]] (Homeland Defense), [[Operation Enduring Freedom]] (Afghanistan), and the [[Iraq War]].<ref name="Icorps"/>

On February 5, 2004, Task Force Olympia was activated as a sub-element of I Corps headquarters with the mission to command forward-deployed units in [[Iraq]]. This marked the first time that I Corps had forward soldiers in combat since the end of the [[Korean War]]. Task Force Olympia included units from all three components of the Army (Active, Reserve, and National Guard) as well as [[Marine (military)|Marine]] and [[Australian Defence Force|Australian]] officers. Task Force Olympia's subordinate units included the 3rd Stryker Brigade Combat Team, [[2nd Infantry Division (United States)|2nd Infantry Division]], which deployed for Iraq on November 8, 2003, and returned to Fort Lewis after one year of combat duty, and the 1st Brigade, [[25th Infantry Division (United States)|25th Infantry Division]], which departed Fort Lewis on September 15, 2004, for one year, and returned in September 2005. On June 1, 2006, the 1st Brigade, 25th Infantry Division, changed its name and became the 2d Cavalry Regiment, Stryker Brigade Combat Team, with its home station in Germany. A new unit then unveiled the colors of its new designation on June 1, 2006: the 4th Brigade, 2d Infantry Division.<ref name="Icorps"/>
