The 7th Infantry Division is a non-deployable administrative headquarters of the United States Army based at Joint Base Lewis-McChord. It is charged with maintaining the capability of two Stryker infantry brigade combat teams, a combat aviation brigade, and a Division Artillery Unit, as well as preparing units for several U.S. Army Pacific yearly exercises. The 7th Infantry Division is the only active-duty multi-component division headquarters in the Army. Brigadier General Bernard J. Harrington commands the division. The 7th Infantry Division is also home to two of the Army's newest enabling battlefield capabilities, the Multi Domain Task Force and the Intelligence, Information, Cyber, Electronic Warfare and Space Capabilities, or I2CEWS battalion.
The division was first activated in December 1917 in World War I, and has been based at Fort Ord, California for most of its history. Although elements of the division saw brief active service in World War I, it is best known for its participation in the Pacific Ocean theater of World War II where it took heavy casualties engaging the Imperial Japanese Army in the Aleutian Islands, Leyte, and Okinawa. Following the Japanese surrender in 1945, the division was stationed in Japan and Korea, and with the outbreak of the Korean War in 1950 was one of the first units in action. It took part in the Inchon Landings and the advance north until Chinese forces counter-attacked and almost overwhelmed the scattered division. The 7th later went on to fight in the Battle of Pork Chop Hill and the Battle of Old Baldy.
