From their post:
Here is a sneak peek at a model currently on the FiB designers workbench. Its a Landkreuzer P1000. This is kind of crazy as you can make out from the photo its about the size of a small town. The vehicle was a concept only and was never built. The FiB guys are nuts though so they decided to build it anyway.'' Hmm now I can crush those Soviets, if I dont sink into a river first''.
