American GI is a group of like-minded historians dedicated to researching and reenacting the history of the United States Army's ground forces during World War Two. Our members reside in the Colorado, southern Wyoming and western Nebraska area and include contemporary military veterans, professionals and individuals with decades of living history and reenacting experience.

Our summer display is the "Defenders of Bataan and Corregidor,"  the American Army in the Philippines in early 1942; our main field impression is the 2nd Armored Division in Europe.  We represent various other infantry divisions at public battles and reenactor-only tacticals, and we remain flexible to change our unit impression to match the time period of an event.
