Sd.Kfz. 251 (Sonderkraftfahrzeug 251) II

SdKfz 251 Ausf D

From early 1943, the SdKfz 251 Ausf D model was developed with the purpose of halving the number of angled body plates, simplifying the design and thus speeding up the production. D models can be easily recognized by their single piece sloping rear (with flat doors).

The standard personnel carrier version was equipped with a 7.92 mm MG 34 or MG 42 machine gun mounted at the front of the open compartment, above and behind the driver. A second machine gun could be mounted at the rear on an anti-aircraft mount.

Variants were produced for specialized purposes, including with anti-aircraft guns, light howitzers, anti-tank guns and mortars or even large unguided artillery rockets, as well as a version with an infrared search light used to spot potential targets for associated Panther tanks equipped with infrared detectors.

Another potentially good design feature of the Sd.Kfz.251 was the large track area, with the characteristic "slack track" design with no return rollers for the upper run of track, and the Schachtellaufwerk system of overlapping and interleaved main road wheels common to virtually all German halftracks of the period. This lowered the ground pressure and provided better traction, giving the Sd.Kfz.251 better cross country performance than most other nations' half-tracked vehicles. However, the interleaved and overlapping main road wheels shared a major problem with the Tiger I and Panther tanks that also used such roadwheel configurations - in muddy or winter weather conditions, such as those during a rasputitsa mud season or the coldest Russian winter conditions, accumulated mud and snow could freeze solid between the road wheels, immobilizing the vehicle.
