103rd Infantry Regiment
Modern Era, United States, Infantry
The 103rd Infantry Regiment belongs to the Army's preserved modern regimental lineage pool. It represents the continuity of unit identity through mobilization, reorganization, and later institutional use.
As with many higher-numbered regiments, its record is best understood through the Army's lineage system rather than through a single continuous field history.
The 103rd Infantry remains part of the Army's historical record of depth, flexibility, and organizational memory.
