155th Infantry Regiment
Modern Era, United States, Infantry
The 155th Infantry Regiment survives as one of the Army's preserved regimental lineages, linking present-day identity to earlier volunteer and National Guard service.
As with many similar units, its continuity is reflected in lineage and honors more than in a continuously active independent regiment.
The 155th Infantry remains part of the Army's stored institutional memory.
