Imperial Navy Breachers

Each time a model in this unit makes an attack, re-roll a Wound roll of 1. If the target of that attack is an enemy unit within range of an objective marker, you can re-roll the Wound roll instead.

Once per battle, when you select this unit as the target of the Grenade Stratagem, you can target one enemy unit visible to and within 18" of this unit that is not within Engagement Range of any units from your army, instead of one within 6"

Once per battle, when this unit is selected to shoot, until the end of the phase, ranged weapons equipped by this unit gain the [Ignores Cover] ability.
