The Pershing was the first operational heavy tank of the United States Army. It was designated a heavy tank when it was designed in WWII due to its 90mm gun which was at the time the largest caliber gun found on an American tank. In 1957 the U.S. developed the M103 tank which had an even larger 120mm gun and the M26 Pershing was re-designated as a medium tank. The tank is named after General John J. Pershing who led the American Expeditionary Force in Europe in World War I.
