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.
An infantry fighting vehicle (IFV), or mechanized infantry combat vehicle (MICV), is a type of armoured fighting vehicle used to carry infantry into battle and provide direct fire support. The Treaty on Conventional Armed Forces in Europe defines an infantry fighting vehicle as "an armoured combat vehicle which is designed and equipped primarily to transport a combat infantry squad, which is armed with an integral or organic cannon of at least 20 millimeters calibre and sometimes an antitank missile launcher."
Infantry fighting vehicles are distinct from armoured personnel carriers (APCs), which are transport vehicles armed only for self-defense and not specifically engineered to fight on their own. Consequently, they possess heavier armament and the attached rifle squad fights mounted more often than in an APC. IFVs also often have improved armour and some have ports which allow the infantry to fire personal weapons while on board.
They are typically armed with a 20 to 40 mm caliber autocannon, a coaxial machine gun and sometimes anti-tank guided missiles (ATGMs). IFVs are usually tracked, but there are some wheeled vehicles too. IFVs are much less heavily armed and protected than main battle tanks, but when equipped with larger cannon or ATGMs may pose a significant threat to all but the heaviest armoured fighting vehicles.
