belching Belching smoke as they charge across the battlefield, Deff Dreads are deadly Ork walkers. Similar way to [[Space Marine Dreadnought]]s, a Deff Dread's pilot must be permanently wired into the machine, Deff Dreads require the skills of both a [[Mekboy]] and a [[Painboy]] to construct. Orks often volunteer to be Aside from basic design elements, Deff Dreads are decorated, armed, and configured in countless ways, each one reflecting the tastes and vision of the Mek who designed it. As for the pilot of a Deff Dread, as is the case with [[Killa Kan]]s, the Ork volunteers are permanently hard-wired directly into Dreads because it will in effect turn him the vehicle itself. Installing a pilot into a massiveDeff Dread involves surgically implanting numerous tubes, powerful nerve probes, cranial jacks, and other, more esoteric bits of mechanical device plugged directly into his brain and destructive machinespinal column.{{Fn|12}}

This is a painful and disorienting experience, which requires an Ork to trade away much of his natural Orkiness, and spend the rest of his days trapped in a claustrophobic, incredibly loud, hot, and uncomfortable metal can, with only a small slit provided to see through, in exchange for raw killing power.{{Fn|2}} The integration of an Ork into a Deff Dread makes the machine very deadly, for these orky machines can move as if they were the pilot's own body. Ork Deff Dreads are loud, stompy and shooty, three things that symbolize Ork warfare and culture. Deff Dreads are normally armed with two huge pincers or saws and two [[big shoota]]s, [[rokkit launcha]]s, [[skorcha]]s or [[Kustom Mega-Blasta]]s.{{Fn|1}} In battle, Deff Dreads act as support units and mobile weapons platforms, working in compliment with mobs or backing up a [[Warboss]] and [[Nobz]]. Even a single Deff Dread brings enough firepower and ferocity to an engagement to tip the scales of even the most fearsome battle in the Orks’ favor. Extremely expensive, Deff Dreads are used sparingly by those Warbosses who can afford them. This irritates none more than the pilots locked within, whose only release from the tedium of being welded inside these machines comes in slaughtering their foes on the battlefield.{{Fn|2}}
