ok, im posting this cos im confused, i work with chaos, but ive got a space marine squad here too, so i was gonna make a rag tag traitor squad, but im wondering, do the beaks mean anything? or r they just another kind of mask? for example if i wanted to make up a hawk lords squad and defile them to attach them to my chaos army, would they need to have beak helmets? or can they have the normal "bulldog" helmets?
