15th Infantry Regiment Battalions
Modern Era, United States, Infantry
This page collects the existing battalion illustrations and additional documented historical battalions of the 15th Infantry Regiment. The historical entries include inactive units and earlier designations; the regimental image identifies entries without a battalion-specific illustration.
1st Battalion, 15th 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 15th Infantry Regiment was constituted on 3 May 1861 during the Civil War expansion of the Regular Army. It served in the western theater and afterward moved into frontier duty and then overseas stationing, most notably in China. Because of that long China assignment, the regiment became known as the "China Hands," one of the most distinctive identities in the U.S. Army's infantry lineage system.
2d Battalion, 15th 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.
That same association continued in Korea. The 15th Infantry deployed with the 3rd Infantry Division and fought in the hard campaigns of 1950-53, helping define the division's combat reputation there just as it had in World War II. This gives the regiment one of the clearest twentieth-century divisional identities of any infantry regiment: its main mid-century wars were fought under the 3rd Infantry Division.
3d Battalion, 15th 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.
In later decades the 15th Infantry continued through battalions rather than as a field regiment in the old sense. Those battalions preserved the regiment's China Hands tradition while serving in the post-Korea and post-Cold War Army. The regiment's history therefore combines Civil War origins, long imperial-era service in China, and two major twentieth-century wars fought as part of the 3rd Infantry Division.
4th Battalion, 15th Infantry Regiment
The 4th Battalion served at Fort Knox with the 194th Armored Brigade from 1987.
After the battalion was inactivated in 1990–1991, two companies continued in service with the brigade until 1995. 15th Infantry Regiment Association.
5th Battalion, 15th Infantry Regiment
The 5th Battalion was activated on 16 June 1989.
It served at Conn Barracks, Schweinfurt, Germany, until being reflagged as the 1st Battalion on 14 June 1991. 15th Infantry Regiment Association.
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.
