Comparing: KV-13 vs. Panther/M10

Development was started in the fall of 1941, under the initiative of Semyon Ginsburg. After successful trials in the fall of 1942, the development of a second prototype was begun.

During the preparation of Otto Skorzeny's Panzerbrigade 150 for the Ardennes offensive, four Panther tanks were disguised as M10 tank destroyers. The tank brigade was to carry out diversions deep behind the allied lines. All vehicles were lost during the battle with the 120th U.S. Infantry Regiment on February 21, 1945.
