Members of the United States Army's 24th Infantry Division with an M24 Chaffee along the Nakdong River front, part of the Pusan Perimeter, in 1950. During the Korean War, the Chaffee fared poorly against the T-34 medium tanks used by North Korean forces, which were better armed, better armored, and better crewed. As the war continued it was therefore used primarily in a reconnaissance role, with fighting handled by heavier, more capable tanks such as the M4 Sherman, M26 Pershing, and M46 Patton.Photograph: Sgt.
