Lol, i've heard this from one of my regular opponents. My explanation is this: The Orks having dissabled the dread would cack it open, scoop out the insides (including the marine) basicaly making it an empty box on legs. Then the meks would go to work filling the box with gubbins to make it work again. Finnaly a grot would be squeezed inside to control it.
well, I realy love what you've done and I am sure when its painted its going to be very impressive. I just have a problem with the fluff. See, tanks and planes are animated things, dead, and can therefor be "looted" and converted. A dreadnought has a human inside and have its own will, and can therefor not be "looted". Its like "looting" a human.
