KettenKrad

At first I couldn't beleive that the puppchen is a anti-tank canon, its size is so small.

I barley started on the kettenkrad, the engine is almost done, but I'm not starting to like dragon that much, they say the engine is paint flat black, but I've never seen a engine completely black, so intead I painted it metalic grey for metal pieces. The puppchen small size makes it fast to build, sould get the canon done and painted in a week, maybe I'll put it in the tiger of firefly scene.

Google is wonderful...took about 10 seconds...

The Püppchen ("Dolly"), a carriage-mounted rocket launcher with breechblock, fires the same 88-mm rocket that is used with the Ofenrohr. The breech prevents any flash to the rear while firing is in progress. To lower the Püppchen's silhouette, the wheels may be removed and the piece left standing on two sled-like rests. In preliminary positions the ground is dug out so that the horizontal section of the lower carriage and trail will lie below the surface. For an all-around prepared position, circular trenches with an inner radius of about 2 feet are prepared. The barrel is left just clear of cover, as is done in the case of the preliminary positions. The lower carriage is dug in and the trail wedged, so that the piece can be fired at an angle of 180 degrees. Positions are prepared in defilade or on reverse slopes, and are well camouflaged. In general, enemy doctrine governing the preparation of positions and the conduct of fire is similar to that for the Ofenrohr, except that only two projectors of the Püppchen type are considered necessary for satisfactory interlocking fire. The maximum effective range of the Püppchen is considered to be 220 yards, although badly dispersed fire up to 275 yards is possible. For this reason the Püppchen, like the Ofenrohr, is employed in the foremost infantry positions. For added protection from artillery fire, the launcher may be detached from its carriage and removed to a shelter some distance away from the prepared position. Alternate positions are prepared only when the terrain restricts the field of fire and provides good cover for the maneuvering piece. In such terrain each position is constructed so that the Püppchen can be run in and out on wheels. Since the Püppchen is harder to conceal than the Ofenrohr, the Germans believe that it is necessary to furnish the larger weapon with antitank protection in the form of obstacles, natural or artificial, supplemented by mines. Because the Püppchen's carriage is not strong enough to stand up under motor towing at high speed, and since horse-draft sacrifices valuable time and involves the problem of replacing animal casualties, the Püppchen generally is transported on trucks and is used only in positional warfare. The Püppchen is a recoilless weapon firing the same ammunition as the Ofenrohr. It has no rearward flash and has a greater range than the Ofenrohr. The 88-mm rocket used in both the Ofenrohr and the Püppchen is heavy enough to cause ammunition-supply difficulties in battle. (A box of three rounds weighs 24 pounds.) This is why the Germans try to build up supplies in all main and alternate positions.

The same can be done for the Kettenkrad.  You can even find a

review of the Dragon kit easily and quickly.

A little research goes a long way.
