GOFF BALL TANK 2/6

I haven't deviantart-ed in years, but I was so shocked to see how few comments this beauty had that I had to log in and post.  This is a work of mad Orkish genius: why add a deffrolla to the front of your tank, when the whole tank can BE a deffrolla?!  I hope you take it only as the sincerest flattery if I try my hand at one of these for my own waaaaagh.
