In 1992, the division transformed into an exercise division under the Army's "Bold Shift" initiative. The new mission is to conduct small unit collective training (LANES) and computerized battle simulation exercises for client units in the First Army East area (a 14 state region). Like the other exercise divisions, the 1st Brigade was designated as the simulations exercise unit, conducting Battle Command and Staff Training for US Army Reserve and Army National Guard units at the battalion, brigade, command, and division levels. This training uses the simulations models used by the Regular Army in conducting WARFIGHTER exercises. The other brigades within the division (2d through 5th depending on the division) conducted field training for units at the squad, platoon, and company levels. In all units, then made up of US Army Reserve soldiers, there were detachments of Regular Army soldiers assigned to manage the day-to-day requirements and planning of exercises as part of the Congressionally mandated Ground Forces Readiness Enhancement (GFRE – popularly known as "Jeffries") program. This program was partially instituted to ensure that reserve component units would have continual training support in order to preclude some of the training and readiness problems that were discovered in the ramp-up, and eventual deployments, in support of Desert Storm.
