The Bundeswehr had originally planned to replace the Marder 1 IFV, starting around the year 2000. However, this plan was cancelled in the light of Germany's reunification and the fall of the Soviet Union. However, an experimental prototype vehicle was developed that demonstrated an unprecedented operational range, cross-country mobility, mounted and dismounted firepower, and armored protection.
The Marder 2 prototype featured a fully stabilized gun with a digital fire control system that could be switched between 35mm and 50mm by changing the barrel and breech assemblies. It was supported with a dual feed system, providing Armor-Piercing and High-Explosive shells. Secondary armament comprised a 7.62mm machine gun.
The vehicle was protected with spaced armor and an interior spall liner, and could carry a complement of ten men. It weighed 43 tons, and was powered by an 8-cylinder turbocharged diesel engine developing 1000hp.
