XIX Corps 3 (U.S. Army) Black Coffee Mug

The XIX Corps 3 refers to a corps-level formation within the United States Army. It is one of the numbered corps formed during the Vietnam War, as the original XIX Corps had been inactivated after World War II. This particular corps unit saw service in the Republic of Vietnam from 1967 to 1970 under various designations and command structures. The XIX Corps 3 was primarily responsible for conducting combined land, air, and naval operations in support of ground forces in the III Corps Tactical Zone, one of four tactical zones during the Vietnam War. It is important to note that the U.S. Army frequently reorganizes its corps and divisions as strategic needs dictate, with some units being deactivated or reassigned over time. The XIX Corps 3 is no longer active in its original form but serves as a historical reference to the structure and operations of the U.S. Army during the Vietnam War era.
