Iraqi held territory with the division's Black Jack Brigade moving north drawing Iraqi divisions out of Kuwait to support the Iraqi units defending in Iraq. This movement was led by the 1st Battalion, 5th Cavalry, from the Wadi Al-Batin to just north of Basra through several Iraqi divisions before stopping. The assault by M1 Abrams main battle tanks, M2 Bradley infantry fighting vehicles, and other support vehicles moved much faster than was thought possible, catching the Iraqi Army off guard. The 13th Signal Battalion was the first unit in the U.S. Army to deploy mobile subscriber equipment (MSE) into combat.

After the division returned from Kuwait, the 1st "Tiger" Brigade, 2d Armored Division was reflagged as the 3d Brigade, 1st Cavalry Division (separate lineage). In response to the continued hostile movements by the Iraqi Armed Forces after Desert Storm, the U.S. Department of Defense ordered successive Operation Intrinsic Action deployments by combat brigades and special forces units to the Iraq/Kuwait border.
