The Marder (German for "marten") is a German infantry fighting vehicle operated by the German Army as the main weapon of the Panzergrenadiere (mechanized infantry) from the 1970s through the present day. Developed as part of the rebuilding of Germany's armoured fighting vehicle industry, the Marder has proven to be a successful and solid infantry fighting vehicle design. While it does include a few unique features, such as the fully remote machine gun on the rear deck, it is overall a simple and conventional machine with rear exit hatch and side gun ports for mounted infantry to fire through. The Marder is currently being replaced by its successor, the Puma.
Around 2,100 were taken into service by the German Army in the early 1970s, but the vehicle in its German variant was not sold to any foreign militaries. As the German Army began to retire older vehicles, the Chilean government agreed to acquire 200 Marders; the government of Greece has considered the purchase of 450 retired vehicles in the past. Argentina uses a simplified and locally produced variant, the VCTP, and has a number of vehicles based on that platform constructed by Henschel and built by TAMSE.
