Modern Era, United States, Infantry
The 111th Infantry Regiment belongs to the Army's modern regimental lineage system and reflects the preservation of unit identity across changing tactical organizations. It stands within the broader framework of twentieth-century mobilization and administrative continuity.
Like many higher-numbered infantry regiments, its history is primarily maintained through lineage, honors, and redesignation rather than through a continuously active field-regiment career.
The 111th Infantry remains part of the Army's larger institutional memory and lineage structure.
A dedicated battalion subpage now collects the regiment's known battalion icons and short battalion sketches for the 1st, 2d, and 3d Battalions. Open the 111th Infantry Regiment Battalions page.
