57th Infantry Regiment
Modern Era, United States, Infantry
The 57th Infantry Regiment was part of the Army's higher-numbered structure used to support overseas commitments and later wartime growth in the twentieth century. It belongs to the broader group of lineages that illustrate the Army's institutional reach beyond its best-known permanent regiments.
Its historical profile is shaped more by the Army's changing organizational system than by one long continuous combat narrative. Through redesignation and preserved lineage, however, the regiment still forms part of the Army's historical record.
That makes the 57th Infantry useful as an example of how the service balanced expansion, contraction, and continuity across the modern era.
