The WWII Sturmpanzer IV "Brummbar" ("Grizzly Bear") was Germany's attempt to mount an infantry support gun on a mobile platform by fitting a large, box-like superstructure to the proven Panzer IV chassis and adding a stout 150mm Howitzer. Proving itself over time to be an excellent fire support vehicle, 298 Brummbars were produced, in four series.

Dragon's "2 in 1" kit of the Brummbar represents a mid-production vehicle, and can be built as either a standard version or a command version with star antenna. This is a "Smart Kit," featuring the highest level of detail with the least amount of hassle. The kit features a highly detailed 150mm gun with rifling, and very basic fighting compartment detail (such as a floor with the correct texture). All hatches can be assembled open or closed. The running gear is all-new for this Brummbar, and includes two options for the idler wheels. Other newly tooled Brummbar-specific parts are included. The schurtzen side skirts are made of scale-thin metal, and can be added or removed individually, even after assembly. Tracks are provided as Dragon's "Magic Trak" indy links, are newly tooled, and are all cleaned up and ready for assembly (glue required). Also includes a fret of photo-etched metal detail parts, wire for the tow cables, clear parts, and Cartograf decals for three versions. No zimmerit included on this one.
