On 24 January 1991, elements of the 84th Division (Training) were activated and mobilized for support roles in Operation Desert Storm. Less than three months later, on 22 March 1991, the elements were returned home. In 1993, reorganization within the Army Reserve brought about the a merger between the 84th and the 85th Division (Training). The move expanded the 84th Division's area of command to include the rest of Wisconsin and Illinois, as well as all of Missouri and Iowa. Soon after, in June 1994, units from the 84th participated in peacekeeping operations as part of the multinational in the Sinai, Egypt, and remained there until July 1995.
