WW II M25 Tank Transporter "Dragon Wagon" with LVT 4

The Models and Materials needed
This is one of my all time greatest favourites. I'm fascinated by this "beast" of a vehicle. I don't know why but somehow I got impressed by this vehicle from the first time I saw it. So it comes as no surprise i'm going to build it. Also I got hold of some instruction video's that show how to operate the winches etc. So a great subject for a diorama. I'm working on some ideas. So let's see where it brings us. First of course is the fabulous model of the M25 from Tamiya. As a load im planning to use the Buffalo Amphibious Tank as it was seen in action in the Netherlands. I used the one from Italeri. AFV-Club has a nice version of this vehicle too. For us as model builders technical manuals are the best sources if it comes to detailing and building correct models. In fact no better reference can be found on the vehicles itself. Another part is of course the in action used vehicle. How was it used, where was it used. Where can i find the right markings. These can be found on contemporary pictues. So it's good to seek out the right pictures, or maybe it's on a piece of video. Search and research is te credo here. Part of the fun of building scale models is research and finding the information you need. This gives much more satisfaction when the project is ready. For myself this is true. Besides the kits themselves i used detailing sets from Plusmodel for the LVT-4 and a detailing set from Eduard for the Dragon Wagon.



The vehicle was officially known as the 40-Ton Tank Transporter Truck-Trailer M25. As the manual TM 9-767 states: The 40-ton, Tank Transporter Truck-trailer M25 is designed for use in recovering a piece of damaged materiel and transporting it to a place where necessary repairs can be accomplished. The M25 unit consists of the tractor truck (M26) and semitrailer (Ml5), the semitrailer being coupled to the tractor by means of a fifth wheel on the tractor, which automatically locks the trailer to the tractor. Air brakes on the trailer wheels and lighting equipment on the trailer are connected to the tractor air and lighting systems by means of air hose and a jumper cable (carried on the trailer). The trailer air brakes and lights are controlled by the driver of the tractor. The trailer air brakes are automatically set in case the trailer is accidentally, or purposely, disconnected from the tractor. The tractor truck M26 is a self-propelled motor vehicle, powered by a 6-cylinder internal-combustion gasoline engine. There are two front and eight rear dual wheels equipped with desert, or combat type, pneumatic tires. The rear wheels are driven by roller type chains operating on sprockets fastened to the wheel hubs. The power to drive the rear wheels is obtained from the engine, through the clutch, main and auxiliary transmissions, rear differential and jackshafts to the drive sprockets which are bolted to the jackshaft hubs. Roller chains on the jackshaft hub sprockets and on the wheel hub sprockets, drive the wheels. The tractor can be used as a recovery vehicle without the semitrailer, since it is equipped with a front mounting winch, a rear tandem winch, and a vertical lifting device. The cab is armor plated and has hinged armor plate covers for the windshield, radiator, doors, and cab windows. All of these armor plate covers are operated from inside the cab and have peep ports. A pintle hook is bolted to the rear end of the frame. Towing shackles are fastened to the front and rear of the frame. A drawbar and whiffletree are carried on the tractor, for recovery operations. Oxygen and acetylene tanks with equipment for welding or cuttings; vise, Pioneer, and maintenance tools are also carried on the tractor.

Where to find information
The best information is that of the Technical Manual of this vehicle, theTM 9-767 from 1944. It gives us a wealth of information on the vehicle itself. A lot of photographs show all parts of the vehicle nesseccary to build and detail it. You can find it in the TM section of this site. Download it if you need it, I can only recommend to use it. Other sources are books, there are a few books that describe the M25 in detail and are also very good starting points. Also a nice video of an M25 in action can be seen on youtube.

A very good source of information yet again for the LVT (4) is the Technical Manual TM 9-776 from 1944. The TM 9-776 states: The Landing Vehicle Tracked, Mk. IV (unarmored) (LVT) (4) is a full-track-laying vehicle of all-steel construction, designed to operate on water as well as on land. The main compartment of the vehicle is an open cargo space. A rear ramp permits the rapid unloading and loading of cargo and personnel. The vehicle is powered by a 7-cylinder, air-cooled, radial engine. A pontoon extending the full length of the track is mounted within the tracks on each side of the vehicle. A closed cab at the front of the vehicle houses the driver and assistant driver. Armament on the vehicle consists of caliber .30 or caliber .50 machine guns, swivel-mounted around the cargo compartment. This Manual also has a lot of good pictures of this vehicle. Some examples below.

The LVT-4was by far the most numerous version of the LVT, with 8,348 units delivered; the US Army received 6,083, and the British Army 500. In 1945 this version was the most common in Germany. Used for crossing the rivers. The picture that inspired me to do this project is the one below on the right where an LVT-2 is loaded off an M25.

This picture was taken during preparations for a river crossing somewhere in Roermond in the Netherlands along the Roer River. It shows an LVT-2.

Here is another one apperantly also in the same city. As is evident in these pictures, the M25 was not only used as a recovery vehicle but also for transporting tasks.


Here are two pictures of US LVT-4's crossing the Rhine. The armored covers for the guns are clearly visible.
