did the Sdkfz 251/10 carry infantry along with its gun crew?
No…
Just to add a little to Manny’s no… [:)] The /10 was intended as the platoon leader’s vehicle in a PanzerGrenadier company up until 1944 when it was replaced with the 251/17. They had a crew of 6 and the rear seats were removed to make room for the ammo storage for the 3.7cm gun so there wasn’t room in the vehicle for anyone aside from the 6 crew. [B] So while you wouldn’t see infantry riding in that particular vehicle it wasn’t out of the norm for it to be around infantry in standard /1 carriers or on foot…all depends on why you ask the question.
