Modern Era, United States, Infantry
This second-pass battalion page ties each battalion icon more directly to the parent regiment's established story. Until a battalion-by-battalion lineage research pass is completed, the copy below should be read as regiment-specific context rather than as a final battalion lineage sheet.
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 138th Infantry Regiment belongs to the Army's preserved higher-numbered lineages and reflects the continuity of unit identity in the modern force. It represents the service's ability to retain names and honors across evolving organizational structures.
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 profile is largely institutional, maintained through lineage, redesignation, and recorded honors.
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 138th Infantry remains one of the many regiments that form part of the Army's wider historical structure.
Research note: This second pass replaces the generic scaffold text with regiment-specific context drawn from the parent regiment page. Dedicated battalion-level lineage research is still deferred to a later pass.
