46th Infantry Regiment Battalions
Modern Era, United States, Infantry
This page collects the existing battalion illustrations and additional documented historical battalions of the 46th Infantry Regiment. The historical entries include inactive units and earlier designations; the regimental image identifies entries without a battalion-specific illustration.
1st Battalion, 46th 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 46th Infantry Regiment was organized in 1917 as part of the Army's rapid expansion for World War I. Its twentieth-century history spans wartime growth, later divisional and battalion assignments, and eventual survival through modern training and institutional roles.
2d Battalion, 46th 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.
The regiment's battalions later served in World War II, Vietnam-era assignments, and in the Army training base. Like several nearby-numbered regiments, the 46th Infantry illustrates how lineages created for the world wars were later preserved inside a much more specialized and flexible force.
3d Battalion, 46th 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.
Today the regiment is remembered less for one single famous battlefield than for its continuity across multiple Army eras, from mass mobilization to modern training and readiness missions.
4th Battalion, 46th Infantry Regiment
The 4th Battalion was deployed during the Chicago civil disturbances in April 1968.
It later served as a basic training battalion at Fort Knox as part of the 4th Training Brigade. Regimental history (Wikipedia).
5th Battalion, 46th Infantry Regiment
The 5th Battalion served in Vietnam as part of the 198th Infantry Brigade, 23d Infantry Division.
It was one of the regiment's combat battalions during the Vietnam War. 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.
