22nd Infantry Regiment
Modern Era, United States, Infantry
The 22nd Infantry Regiment grew out of the wartime and postwar reorganizations of the nineteenth-century U.S. Army and served through frontier duty, overseas expansion, and the shift to division-based warfare. Like many old regular regiments, its history runs from the post-Civil War Army into the overseas campaigns of the turn of the century.
In the twentieth century the regiment's lineage was carried mainly through battalions rather than a continuously active regimental headquarters. Those battalions served in the divisional Army of the world wars and later in the Cold War force, preserving the regiment's history even when the traditional regimental structure was broken up.
The 22nd Infantry is best understood as one of the enduring regular lineages of the Army: less famous than some neighboring regiments, but representative of the long institutional continuity that links frontier soldiers to the modern battalion-era Army.
