You need a half-track-unit in your mod? Unfortunately, there is no "TankTruckDrawModule" in CnC3TW, like in Generals.
But its not difficult to create a halftrack in TW.
The trick is, to combine two draw modules: TankDraw and TruckDraw.
First, make your model of a halftrack and texture it, give the treads an own texture-file.
Then, we have to separate the truck-part and the tank-part.
The truck-part is the whole model except the treads (tire animation). The treads are our tank-part (tread animation).
Save your model. After this, select the treads and delete them. Save the treadless model under yourmodelname_truck.
Now, reopen your complete model or undo the tread deletion. Select all except the treads and delete it. Save the treads under yourmodelname_treads. Export both parts to w3x-files (3dsmax-Users have to change the commas to dots inside w3x-Files after exporting). Copy the two w3x-files and the model's textures in your Modsdk/Art/.../ -folder and create the xml-files for the textures.
It's time to create the unit-xml. It can look like this: (just an example, I removed for this tutorial unnecessary code parts)
Code:

At last, create all necessary entries and xml's 4 your unit, compile and play your mod.
Its my solution for a halftrack-unit. Proposals and better solutions welcome!
The NOD-Reckoner in "Kanes Wrath" is a halftrack in my opinion. The code of this unit could be include a better solution.
Note: Sorry 4 my bad English
