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.
From that year to 1994 it was one of only four (later three) combat Infantry brigades in the Army Reserve.
As a separate brigade, the 187th wore its own shoulder patch rather than the 94th Division patch its members had previously worn.

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.

The brigade's headquarters was relocated on 25 October 1971 to Wollaston, Massachusetts and on 13 July 1976 to Fort Devens, Massachusetts.
