[2] The 94th Division was disbanded in the early 1960s, as part of continuing Army Reserve force reductions.

Thus to add flexibility to the force, and to preserve a general officer billet, the 187th Infantry Brigade was reactivated in the Army Reserve as a separate brigade on 7 January 1963 with headquarters in Boston, Massachusetts.

Cold War plans called for the brigade to deploy to Iceland as part of the Iceland Defense Force if a confrontation between NATO and the Soviet Union occurred.

On 14 April 1994 the 187th Infantry Brigade was inactivated as part of the Army-wide post-Cold War reductions.

[7] The 187th Infantry Brigade was reactivated as an initial entry training unit at the U.S. Army Maneuver Support Center of Excellence, Fort Leonard Wood, Missouri on 23 January 2007 from the 3rd Training Brigade and inactivated on 17 May 2007.
