Adorned in honor of the Chaos gods, this Tainted Heavy Bolter replicates the staggering firepower of emplaced weapons in a form portable by a mighty Chaos Space Marine. By planting his feet, the wielder can gain increased rate of fire and accuracy at the cost of mobility.
Heavy bolters are generally used for anti-infantry or fire support roles. It fires a round comparible to the size of a human fist, which is considerably larger than that of the standard bolter shell, with more propellant and longer range, making it capable of destroying light vehicles. Because of its high rate of fire, jamming is often a problem. Like all bolt weapons, heavy bolters require regular maintenance and ancient litanies to appease their spirits.
The most modern version of the heavy bolter in widespread use is the Astartes Mk IVc. The weapon goes through rounds very quickly using either a disintegrating belt or 40-round high capacity box magazine. It can be fitted with special ammunition or fitted with a bipod to be used in a sustained fire capacity.
