Inferno Cannon

Place the Heavy Flamer Template as normal, then roll an Artillery Die and move the template that many inches straight ahead. The normal rules for templates apply to models touched or covered by the template at any point in its movement. Models surviving a hit may still catch on fire.
In addition, crew inside vehicles affected by the Inferno Cannon may be affected even if the armour is not
penetrated. For each model on board, roll D6; on a 6, the model takes 1 wound with a –1 save modifier. If a
location catches fire, you must continue to test for the crew until the flames go out.
