Backstory

Flamers are flamethrower weapons, capable of unleashing a liquid incendiary chemical that bursts into flames as it leaves the weapon. Similar flame-based weapons are used by several of the intelligent races and their militaries across the Milky Way Galaxy. Flamers are valued for their ability to destroy many enemies at once, regardless of any protective cover they possess. Both Flamers and the more compact Hand Flamers are considered assault weapons due to their relatively short range. Loyalist Space Marine and Chaos Space Marine flamers fire a mix of highly volatile liquid chemicals which ignite with the use of a pilot light. The flaming chemical sticks to its target and continues burning on its own accord – those who are not killed instantly die horribly as the super-hot chemical continues to burn through their bodies. The most common flammable substance used as Flamer fuel is Promethium, which is a petroleum-like jelly that can stick to a target and is very similar to the twenty-first century incendiary called napalm. The flamer fires a burst of expanding flames, making the weapon effective at killing enemies in cover.
