The Brummbär ("grouch") was employed to provide fire support against "soft" targets.

The design was based on the chassis of the Panzer 4. This was fitted with an armoured superstructure featuring a short-barreled Sturmhaubitze assault gun. But the weight of the gun and the armour were too heavy for the chassis. This led to frequent breakdowns of the suspension and the transmission.

The 100 mm front armour and 50 mm side armour plates provided effective protection when needed. It was, however, rarely intentionally employed against enemy tanks. The Brummbär had been primarily designed to engage fortifications and infantry crouds under the cover provided by other tanks.

The shown vehicle has steel road wheels. The road wheels would usually have been fitted with rubber tyres but rubber was becoming scarce in the German sphere of influence. The rubbe casing was therefore omitted which caused noise and vibrations inside the vehicle.
