133rd Infantry Regiment
Modern Era, United States, Infantry
The 133rd Infantry Regiment reflects the Army's practice of preserving unit identity through lineage and honors across repeated organizational change. It stands within the modern regimental system rather than the older permanently active regular establishment.
Its historical profile is primarily institutional, carried through redesignation rather than by one uninterrupted field-regiment story.
That continuity still gives the 133rd Infantry a place in the Army's long historical record.
