Vann the Red Seems to be a Lt. General Laurens, skill 2, max skill 3. Not a brilliant choice of leader.
ClinOps That's National Socialist chaos space marines curtesy of Sturmbannführer Duhrn [5 points to the first person to explain this reference] and I suspect the HA can be classified as "enough". I guess thats "V" points for identifying a Mark V Defiler. Now which chapter does it belong to.
Profane I'm going for the classic division + non-divisional troop count of 20,000 and hence an estimate of 800 divisions - currently.
Lifeless I'm not entirely sure of the scale but I would guess the Defiler is about 15' high and I wouldn't want to be ducking under its legs.
Tribolute Sorry but we seem to be moving on from the "vespene" gas references. Now all I need to do is find a relic to occupy along with all the strategic points.
