All of this work was done by Time DuPertuis of Armorcast, originally intended for Ork use, but we will not hold that against him.
The length is about 2x the width, the width is about 2x the height, which is about equally divided between tracks and armor. The hull is about equally divided between the front Dakka-Dakka zone and the rear Berserker-Box zone. The angle of slope of the front and rear armor is also symmetrical.
This 4-fold symmetry of 1:2 relationships yields the number 8, the number of arrows in the Chaos Star and the Sacred Number of Khorne. And thus we shall name our APC The Mouth of Khorne.
So what does all this accomplish? Fulfillment of Hungry Ghost's desire to have a land-version of the Korean Turtle-Ships (Geobukseon or Kobukson) used against Japanese invasions by the legendary Admiral Yi Sun-sin in the late 16th century. They were based on 15th century Turtle-Ships, and intended for use as a close-assault vessel.
Here we see another Turtle-Ship. There is debate as to whether Geobukseon were the first ironclad vessels used, but no debate that they had lots of spikes and dragon heads attached to the front that released noxious smoke or cannon fire. Dragon heads and lots of spikes are mandatory for any armored vehicle in the Legios Moriad XIV, so the final form of The Mouth of Khorne will more closely resemble the mighty turtle.
The Hungry Ghosts will tolerate no comments about Dwarfs and Turtles sharing speed-impairments; all comparisons shall be regarding powerful armor and an ability to traverse even the roughest of terrains.
Another view of the Burnt Scorpions emerging from The Mouth of Khorne. Hungry Ghosts is still not sure what the final carrying capacity for the APC will be. But it probably won't be finished for a couple of years, so there is time to think about that. A Chaos Squat equivalent to the Imperial Crassus Armored Assault Transport may be thing to do.
One more just because.
