123rd Infantry Regiment
Modern Era, United States, Infantry
The 123rd Infantry Regiment reflects the Army's preserved higher-numbered lineage system, in which names and honors were kept alive through redesignation and organizational change. It is part of the service's long institutional continuity in the modern era.
Its history is chiefly visible through the lineage framework rather than through a single continuous field-regiment narrative.
The 123rd Infantry remains one of the many lineages that supported Army depth and continuity.
