Breaking off from the traditional way I present these type of models, I made a few TIE Tanks for the Expanded Fronts mod as was requested. I took some inspiration from preexisting land-based TIEs', like the Mauler and Crawler. This time I added rocket pods as was specifically requested. The overall shape is like that of the Tie Advanced, while the canopy area is reminiscent of a B-29 Superfortress. A hatch is present on top for the driver to enter and exit with relative ease. One of the working names of one of the rocket-based tanks is Tracked Missile Launcher, or TR-ML for short.
I also included a couple of images of how these tanks will be presented in-game. Mod link: www.moddb.com/mods/star-wars-g…
Of course there isn't a Wookiepedia entry on these tanks since they are conceived just for this mod, but it is pretty obvious to see what roles these tanks play on the battlefield.
