The XXII Corps is a corps of the United States Army, serving under the Unified Command Plan as part of the United States Army Pacific (USARPAC). Originally activated during World War II, it played significant roles in various campaigns, including Normandy and Okinawa. Post-World War II, the corps was inactivated, only to be reactivated during the Korean War and again in 1983 for the Cold War era. The XXII Corps is a vital component of USARPAC’s ability to respond effectively to crises across the Asia-Pacific region. Its headquarters are located at Joint Base Pearl Harbor-Hickam, Hawaii.
