The 121st Evacuation Hospital was a distinguished U.S. Army medical unit with a storied history dating back to World War II. Originally activated in 1943, the unit provided critical medical care to wounded soldiers in both the European and Pacific Theaters. During the Korean War, the 121st EVAC became renowned for its frontline surgical capabilities, operating near Seoul and later establishing a permanent presence as the 121st Combat Support Hospital. The unit continued its legacy of excellence in subsequent conflicts, becoming a cornerstone of U.S. military medical support in the Pacific region.
