Somewhere outside Rome on June 5, 1944, a U.S. soldier from the 5th. Army examines what is left of a German 7.5cm PaK40/2 auf Fahrgestell Panzerkampfwagen II (Sd.Kfz 131) tank destroyer which was, mercifully, simply called the Marder II. The need to both bolster and improve tank destroying capability resulted in two tank destroyers utilizing the chassis of the Panzerkampfwagen II light tank.
The first version was designated the Panzer Selbstfahrlafette 1 für 7.62cm PaK36(r) auf Fahrgestell Panzerkampfwagen II Ausf D¹ und D² (Sd.Kfz 132). Sometimes (again, mercifully) known as the LaS 762, this tank destroyer utilized Panzer II ausf. D and E as well as Flammpanzer II (a flamethrower variant of the Panzer II) chassis and mounted a captured Soviet 76.2mm F-22 Model 1930 field gun rechambered to fire the 75mm round used by the potent PaK 40 anti-tank gun. The LaS 762 was a stop-gap design while more purpose-built tank destroyers were designed and put into production. It was characterized by its tall profile and 201 vehicles were converted between April 1942 and June 1943.
The second version was the Sd.Kfz 131, a more dedicated tank destroyer design, and it used war weary Panzer II ausf. A, B, and C chassis (but would later use factory "fresh" ausf. F chassis). The Marder II had the excellent 75mm PaK 40 gun as its main weapon. All told, 651 Marder II were produced between June 1942 and March 1944 and saw service on all fronts (though the majority were deployed to the Eastern Front). Both the German Army (Heer) and Waffen-SS were heavy users of the Marder II, equipping the panzerjäger abteilungen of panzer divisions. In addition, some Luftwaffe ground forces used the Marder II in their own tank destroyer units.
The Marder II in the photograph has lost its entire superstructure save the forward portion and the front of the hull has been completely blown out as has the back of the vehicle. Given the extent of the damage and most notably by the burst barrel of the PaK 40, this particular Marder II was destroyed by the crew using demolition charges. This was not too uncommon when the vehicle could not be recovered from whatever circumstance disabled it (mired in the ground, mechanical breakdown, or battle damage) and so blowing the vehicle up denied its use by the enemy.
