I CORPS

I Corps, also known as "America’s Corps," is a distinguished field army corps of the United States Army with a lineage dating back to World War I, when it was first activated in 1918. The corps played pivotal roles during World War II, participating in campaigns throughout the Pacific theater, including New Guinea and the Philippines. Reactivated for the Korean War, I Corps commanded United Nations forces in several major operations and remained a key component of U.S. military presence in Korea during the Cold War. In the 21st century, I Corps has been headquartered at Joint Base Lewis-McChord, Washington, and has deployed units in support of operations in Iraq, Afghanistan, and the Asia-Pacific region, emphasizing its enduring commitment to joint and multinational operations.
