If you've even remotely started learning about scripting, then you'd know that what you're asking for has been one of the most annoying questions ever to hear on this board.
The answer is:
Yes, I do have a moving tank script.
No, you cannot get some help with this, because in order for it to work properly, you would need V1.07 of my Mod, which isn't released yet since it's still in development.
Of course, you could always try the "movefore" command in a script and attach it to your tank. That might give some mediocre results.
