Named after General Adna Chaffee, the M24 "Chaffee" was a light tank that replaced the M5 "Stuart" tank seen in the background. The M24 saw combat in the U.S. Army at the end of WWII, during the Korean War, with French forces in Indo China and Algeria and with Pakistan against India. Over 20 other countries used the M24 with Norway, Chile and Uruguay upgrading their tanks with more powerful engines and guns. Weighing in at 20 tons with a crew of 5 the Chaffee mounted a 75mm gun and three machine guns. The 75 mm was a big improvement over the 37mm mounted on the M5 Stuart, but the M24 was really a recon and infantry support tank and not meant to fight other tanks. This was brought home during the Korean War when M24s from the U.S. occupation forces in Japan were rushed to the peninsula in 1950 and took a beating from North Korean T-34s. The good speed, wide tracks and torsion bar suspension made M24s more effective during the fighting withdrawal to Pusan in hit and run tactics to slow down the North Koreans. Medium and heavy tanks were brought in to handle the Soviet made armor used by the Communist forces. These included the late model M4 Sherman mounting the long barrel 76mm gun, the 90mm gunned M26 Pershing and M46 Patton, as well as the British Centurion with the 84mm/20 Pounder. Like the other photos in the Tank-O-Rama series, this picture was taken at the 1st Division Museum at "Cantigny" in Wheaton, Illinois.
