Super heavy weapons

Super heavy weapons are ones that don't have a preset Firepower value or sometimes don't even have a Firepower value at all. Super heavy weapons are most commonly found on war engines, but some specialist vehicles like tank hunters or long range artillery units may be armed with them as well. Note that these rules only tell you about the effects of these weapons, the range of the weapons depends on the unit carrying them.

Super heavy weapons can be fired at any target within range, so, for example, they can pick out individual targets within a detachment. Super heavy weapons which are used by units making an Assault must roll a 4 or more on a D6 in order to lock on and be able to fire in the Shooting phase. Units in Overwatch may re-roll misses for super heavy weapons as usual. In firefights a super heavy weapon which doesn't have a basic Firepower value always counts as having a Firepower value of 1 instead.

Super heavy weapons and Blast markers

When a detachment with super heavy weapons fires it places Blast markers on the target detachment. The number of Blast markers placed depends on the number of super heavy weapons fired by an attacking detachment before modification for Assaulting, Blast markers etc.

Look up the number of super heavy weapons being fired on the Super Heavy Weapons Blast Markers table to find out how many Blast markers are generated. If a detachment is firing with both Firepower and super heavy weapons it places Blast markers for both attacks.

Super Heavy Weapons Blast Markers table

Super Heavy Weapons Firing	Blast Markers
1–3	*
4–8	1
9 or more	2
* = 1 Blast marker if you score any hits, otherwise none.

Each Blast marker on a detachment reduces its super heavy weapon shots or Firepower by one each. The detachment's firepower is always reduced first, and if the Blast markers exceed its Firepower the remainder are deducted from its super heavy weapons shots.
