Beginning in 1980, the 6th Battalion, reactivated, served as component of the Opposition Force at the [[National Training Center]] at [[Fort Irwin]], California, as part of the 177th Armored Brigade until the battalion was reflagged as the [[52nd Infantry Regiment (United States)|1st Battalion, 52nd Infantry Regiment]] in 1988.

The 4th Battalion, 31st Infantry Regiment, was reactivated at Fort Sill, Oklahoma to support the Field Artillery School and the 6th Battalion was reactivated at Fort Irwin, California, serving there until its inactivation in 1988. In 1995, the 4th Battalion was inactivated at Fort Sill and reactivated as part of the 10th Mountain Division at Fort Drum, New York the following April. It is now the regiment's only battalion on the active rolls.
