Havoc
Havocs are the Chaos Space Marines' equivalent of Devastators. Like their loyalist counterparts, these guys drag the heavy weapons into battle, laying out copious amounts of fire to support their brethren. Havocs can equip most of the goods that Devestators can, though you won't be seeing any plasma cannons on these guys. Unlike loyalist marines, Havocs still have access to autocannons that can be lugged around by a single marines, which they are more than happy to bring along with them. They also like to stick big ass bayonets on their guns, just in case the opportunity to stab something with a lascannon presents itself.
