Heavy Weapons with [HEAVY] in their profile are known as Heavy weapons. Each time an attack is made with such a weapon, if the attacking model’s unit Remained Stationary this turn, add 1 to that attack’s Hit roll.
Indirect Fire Weapons with [INDIRECT FIRE] in their profile are known as Indirect Fire weapons, and attacks can be made with them even if the target is not visible to the attacking model. These attacks can destroy enemy models in a target unit even though none may have been visible to the attacking unit when you selected that target.
If no models in a target unit are visible to the attacking unit when you select that target, then each time a model in the attacking unit makes an attack against that target using an Indirect Fire weapon, subtract 1 from that attack’s Hit roll, an unmodified Hit roll of 1-3 always fails, and the target has the Benefit of Cover against that attack. Weapons with the [TORRENT] ability cannot be fired using the [INDIRECT FIRE] ability.
