109th Infantry Regiment Battalions

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.

1st Battalion, 109th 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 109th Infantry Regiment is one of the Army's preserved modern-era lineages, representing continuity of identity across periods of mobilization, reorganization, and force reduction. Its place in history lies in that larger system of organizational preservation.

2d Battalion, 109th 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.

As the Army shifted toward battalion- and brigade-based formations, the 109th Infantry's identity was maintained through lineage and honors rather than through constant regimental field service.

3d Battalion, 109th 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.

That continuity keeps the regiment within the Army's broader institutional heritage.

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.
