The 9th Mission Support Command (MSC) was originally designated as the IX Corps (Augmentation) and was organized on January 16, 1962. At that time it was an integral part of the Active Army’s IX Corps. The IX Corps headquarters was first constituted on July 29, 1921 in the Organized Reserves to provide Command to Reserve Units. Though the Corps was not activated, it remained on the organizational rolls of the Army, to be called on when needed. On October 1, 1933, the Corps was moved to the Active Duty roster, though it remained deactivated.

In 1940, it was activated at Ft. Lewis, Washington. It immediately began training of combat units in preparation for deployment. One year later, IX Corps took Command of the Camp Murray staging area in Washington, responsible for training Army National Guard forces, Active Duty and Reserve Units. Following the attack on Pearl Harbor in late 1941, IX Corps was assigned to defensive duties on the West Coast of the United States. In 1944 it was deployed to Leyte Gulf, Philippine Islands, where it was placed in charge of preparing the US Tenth Army for the invasion of Okinawa. In Leyte, IX Corps was tasked with the planning of Operation Olympic, the invasion of the home islands of Japan, specifically the island of Kyushu. After World War II it was assigned to the Eighth U.S. Army for occupation duty in Japan.

The IX Corps was inactivated in March 1950, but was reactivated in August that same year at Ft. Sheridan, Illinois. It was sent to Korea, where it participated in the successful expulsion of communist forces from South Korea. For its outstanding service, the unit was awarded two Republic of Korea Presidential Unit Citations and nine campaign honors. IX Corps fought hard and well in Korea. The unit was on the line the entire conflict and always inflicted more casualties on the enemy than she sustained. Examples of valor and sacrifice were numerous. An example of which is the Distinguished Service Cross won by IX Corps Commander Lieutenant General Reuben E. Jenkins at Chorwon. In 1954, the unit was ordered back to Japan. In 1956, it redeployed to Okinawa to become part of HQ, Ryukyu Islands. In 1961, the IX Corps be-came a Major Subordinate Command of U.S. Army, Pacific. At that time it was an integral part of the Active Army's IX Corps, and participated in Command Post Exercises with the Corps for its Annual Training. The nature of these exercises in the 1960s was unique in that IX Corps now had a Reserve element in Hawaii and an active duty element in Okinawa. This made for excellent cooperation and coordination between the Army Reserve and the Active Army. The exercises were realistic. Southeast Asia Treaty Organization (SEATO) exercises in Thailand occurred as the Vietnam War was raging. IX Corps Soldiers had a better understanding of the nature of the Vietnam War before the rest of the Army. These exercises included the continuing Yama Sakura with Japan, Coral Sands in which IX Corps troops participated in an amphibious as-sault on Molokai with components of the Active Army and Navy, Trupenamt II, and Triad 81 with Australian and New Zealand Forces.

On April 27, 1987, the Command was re-designated IX Corps (Reinforcement). On October 1, 1995, the Command was renamed 9th U.S. Army Reserve Command following the inactivation of IX Corps, a month earlier at Camp Zama, Japan. The Command moved to its current location at Fort Shafter Flats from Fort DeRussy in December 1997.

The organization experienced several years of reorganization and restructure to establish a more relevant, ready, and indispensable Pacific Army Reserve Force. As a result the Command was re-designated the 9th Regional Support Command on January 31, 1998, then re-designated as the 9th Regional Readiness Command on November 4, 2002 and again re-designated to its current organization as the 9th Mission Support Command (MSC) on April 16, 2008.
