Comparing: M56 Scorpion vs. E 25

The M56 SPG was intended to support airborne units as a light tank destroyer that could be transported by cargo planes or inserted by parachute or glider. The vehicle was mass produced from 1953 through 1959, but it was not popular and was soon replaced by the Sheridan light tank. The Scorpion was occasionally used to provide artillery support in Vietnam.

Development of the E 25 was a part of the "E" program, aimed at unifying the manufacture of the German armored forces. The program was supervised by the Waffenprüfamt 6 committee, directed by General Kniepkamp. The E 25 was developed by the Argus company (Karlsruhe, Germany). No prototypes were manufactured, the vehicle never underwent trials or saw service. However, according to some sources, by January 23, 1945, several hulls were produced and remained in Katowice waiting for trials.
