87th Infantry Regiment Battalions
Modern Era, United States, Infantry
This page collects the existing battalion illustrations and additional documented historical battalions of the 87th Infantry Regiment. The historical entries include inactive units and earlier designations; the regimental image identifies entries without a battalion-specific illustration.
1st Battalion, 87th Infantry Regiment
This entry now anchors the battalion page in the regiment's origin or defining early identity, giving the 1st Battalion slot a more specific historical frame than the first scaffold pass.
The 87th Infantry Regiment is best known through the mountain-infantry tradition of the modern U.S. Army. It became closely associated with the 10th Mountain Division and with the specialized cold-weather and mountain warfare identity that set that division apart from most of the Army.
2d Battalion, 87th Infantry Regiment
The 2d Battalion entry uses the regiment's middle or operational arc to give the page a clearer sense of how the parent unit developed over time.
Its modern history therefore differs from many other higher-numbered regiments. Instead of serving mainly as an abstract lineage, the 87th Infantry remained tied to one of the Army's most distinctive active divisions and later carried that identity into the post-Cold War era.
3d Battalion, 87th Infantry Regiment
The 3d Battalion entry now carries the regiment into its later or enduring modern identity, tightening the page around the way the lineage is remembered in the modern Army.
The regiment stands as one of the clearest examples in this number range of a lineage with a recognizable specialty and continuing operational identity.
4th Battalion, 87th Infantry Regiment
The 4th Battalion served with the 25th Infantry Division at Schofield Barracks from 1986 to 1995.
Its missions included Sinai peacekeeping in 1991 and relief work after Hurricane Iniki in 1992. Regimental history (Wikipedia).
5th Battalion, 87th Infantry Regiment
The 5th Battalion was activated in Panama in May 1987 with the 193d Infantry Brigade, replacing the 1st Battalion, 187th Infantry.
It fought in Operation Just Cause in 1989 and was inactivated in September 1999. Regimental history (Wikipedia).
Research note: The added historical entries cite their sources individually. Regimental illustrations are labeled as such. An earlier battalion designation can continue through another battalion or a separate battery; these relationships are identified in the entries. The original three entries are retained; the additional entries do not treat regimental campaign credits as evidence that every battalion fought in those campaigns.
