Modern Era, United States, Infantry
The 122nd Infantry Regiment was one of the higher-numbered lineages preserved within the modern Army's infantry system. It reflects the practice of maintaining unit identity across mobilization, redesignation, and later organizational change.
Like many regiments in this range, its significance lies more in continuity than in one uninterrupted independent field-regiment history.
That continuity keeps the 122nd Infantry within the Army's wider institutional heritage.
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 122nd Infantry Regiment Battalions page.
