Warhammer 40K Tactics

[Dervag]

I say its possible with some sort of incendiary missile type of weapon which orientates itself in the preferred direction right before impact. But the hellhound has a flamethrower like weapon modelled on it, fuel tanks and all, I cant see how that would work. Or are we talking it being possible in the rules?

In real life, flamethrowers do not produce an arc of flame. They produce a stream of flaming liquid, like water from a firehose. Of fire.

The arc effect we normally see from WH40k infantry flamers would represent the guy with the flamer playing the stream of fire from his weapon back and forth across the arc described by the template.

A Hellhound's heavy flamer shoots the burning liquid much farther. My image is that it fires the liquid on a ballistic arc. Then when the stream hits the ground, it sprays outward in a big zone matching the shape of the template.
