About the Subject (from Wikipedia)
“The M26 Pershing was a heavy tank/medium tank of the United States Army. It was used in the last months of World War II during the Invasion of Germany and extensively during the Korean War.
The M26 was intended as a replacement of the M4 Sherman but a prolonged development period meant that only a small number saw combat in Europe.
The M26 was the culmination of a series of medium tank prototypes that began with the T20 in 1942, and it was a significant design departure from the previous line of U.S. Army tanks that had ended with the M4 Sherman. Several design features were tested in the prototypes. Some of these were experimental dead-ends, but many become permanent characteristics of subsequent U.S. Army tanks”.
