91st Infantry Regiment
Modern Era, United States, Infantry
The 91st Infantry Regiment was one of the many numbered lineages preserved within the Army's modern force structure. It reflects the service's ability to retain organizational identity beyond the small set of continuously active and famous field regiments.
Its historical profile is mainly institutional, shaped by the Army's cycles of expansion, redesignation, and contraction in the twentieth century. Through lineage and honors, however, the regiment remained part of the Army's historical record.
The 91st Infantry is thus one of the supporting lineages that reveal how broad the Army's organizational base became in the modern era.
