This is a multimedia kit comprised of 15 sprues, magic tracks, one photo etched fret, decals, and the set of instructions that need to be reviewed very carefully before gluing any parts together. You can build the howitzer as either installed in the vehicle or in the towed format. The vehicle looks very plain without the gun mounted, so that is how I built the model.
Most Dragon models today are a collection of old sprues and new sprues added to create a new kit variant. In this case, Dragon has not done so; only the road wheels, suspension and a couple of pioneer tools are from prior kits, and everything else is new molding.
