A model with this special rule has the Hatred special rule against Daemons of Slaanesh or models with the Mark of Slaanesh. Furthermore, when making Fear tests, a unit containing at least one model with this special rule suffers a -1 penalty to its Leadership if it is engaged in combat with a unit that contains at least one model with the Mark of Slaanesh or the Daemon of Slaanesh special rule.
A unit comprised entirely of models with the Battle Focus special rule can either shoot and then Run, or Run and then shoot, in the same Shooting phase. The unit must complete both actions before you move onto the next unit - otherwise the chance to make the second action is forfeit. A model cannot Run if it fired a Heavy weapon during the same Shooting phase unless it has the Relentless special rule. Similarly, a model that has Run cannot then fire a Heavy weapon in the same Shooting phase unless it has the Relentless special rule. Models that cannot Run gain no benefit from the Battle Focus special rule.
A unit composed entirely of models with this special rule can re-roll one or more of the dice when determining Run moves and charge ranges (such as a single D6 from a charge range roll, for example).
At the start of each Fight sub-phase, a unit in base contact with one or more enemy models that cause Fear must take a Leadership test (called a Fear test) before any blows are struck. If the test is passed, all is well and there is no effect. If the test is failed, the unit succumbs to fear - all models in the unit have their Weapon Skill reduced to 1 for the remainder of that Fight sub-phase. Note that a model that causes Fear is not itself immune to Fear, and will still need to take a Fear test if it is base contact with any enemy models that cause Fear.
