Comparing: Panther/M10 vs. A-44

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.

The project was developed at Factory No. 183 by engineer I.S. Ber in April 1941. The vehicle was to be manufactured in three different versions with different armor, armament, combat weight, and speed. The prototype was scheduled to be built by the beginning of 1942. However, the project was discontinued due to the outbreak of the Soviet–German war.
