Modern Era, United States, Infantry
This page collects the existing battalion illustrations and additional documented historical battalions of the 135th Infantry Regiment. The historical entries include inactive units and earlier designations; the regimental image identifies entries without a battalion-specific illustration.
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 135th Infantry Regiment belongs to the Army's preserved set of higher-numbered infantry lineages. It reflects the way the service maintained depth, honors, and continuity across periods of mobilization and later reorganization.
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 identity was preserved mainly through the lineage system rather than through one continuous field-regiment career.
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 135th Infantry therefore forms part of the Army's broader institutional narrative in the modern era.
The 4th Battalion was organized on 1 April 1963 as an element of the 47th Infantry Division in the Minnesota Army National Guard.
It disappeared from the regimental organization in the February 1968 reduction to two battalions. 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.
