I've used these guys quite a bit so I think it is about time we adressed these overgrown apes:
Black Ogrun Boarding Party
These guys are cheap, multiwound models. For cost of 6, they fall in the same line of cheap infantry that Cryx is known for. Suprisingly, their speed is the same as Mcthralls, faster than drudges, but not as fast as the witches. So what good are they? Offensively with only at most 5 guys in the group, they are a little lack luster at taking out masses of troops. But the POW of their weapons is pretty decent, and can easily damage lights and put serious dings in lower ARM heavies. Add to this the fact that the Ogrun have CRA and drag and they add some tricks to the forces of Cryx. Like dragging a jack to be converted by the Withershadow combine or pulling a beast out of a Warlocks control area. Defensive-wise they aren't terrible, but not that great either. They have an average DEF, ok armor and 8 wounds, making them somewhat harder to one-shot (barring weapon master or other DAM buffs). They make for cheap screen for our Medium sized casters, as well as a a great unit when fighting jacks and multiwound models. But against masses of infantry they are somewhat sub par (You'd be better off with witches, drudges or Mcthralls).
