The Marder is an infantry fighting vehicle operated by the German Army as the main weapon of the Panzergrenadiers units(mechanized infantry) from the 1970s through to the present day. 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
