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 39th Infantry Regiment was organized during World War I and became one of the regiments shaped entirely by the twentieth-century Army. Its most important service came through divisional assignments rather than through a long independent regimental tradition.
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 and its battalions later appeared in World War II, Vietnam-era service, and the training and operational Army that followed. As with several other lineages in this number range, the regiment's history survives mainly through battalion descendants and unit tradition rather than through one uninterrupted regimental combat 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 39th Infantry reflects the Army's move into industrial-era warfare and then into the later modular force, where old regimental names remained important carriers of institutional memory.
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.
