Panzer: Sdkfz 251/9, Ausf C "Stummel"
A fine photo of this fire support half track in wintry surroundings.
The 251/9 mounted a short 75 mm gun (initially leftovers from Stug III and Panzer IV production when it switched to the long barreled version)
The "Stummel" (stumb) provided some extra "bite" to reconnaissance units if they encountered strong enemy forces. Note the tactical and unit markings on the front armour plate (the unit symbol is unknown to me) and the troopers wearing the reversible winter hood for extra warmth and protection, a Sdkfz 250 is also visible to the right.
