Screamers of Tzeentch

Vicious warp predators, Screamers of Tzeentch were often unleashed into reality by Stygian Militia units.  With their uncanny speed and horrific bite capable of ripping open armored vehicles they added tremendous punch to stygian militia assaults.  Furthermore they would wreck havoc in Imperial rear areas after they pierced the Imperial main line of resistance.  Screamers were often seen hunting the battlefield in packs of three or more.  They were quick to become priority targets amongst Imperial armor crews.
