Well, assuming he can have that many(check the points you're playing, because dreadnaughts are support) you should be able to match each one with a carnifex. Give each one Sharpened Claws and a defensive biomorph like Voltage field, Warp field, Hardened Carapace, or toughened exoskeleton. A carnifex by itself is enough to kill a dreadnought. It matches the dreadnought in WS and S, but the carnifex has 1 more Attack die, and with 10 wounds, can suffer more damage.(posted 9633 days ago)
