Grenade Pack

Any time a unit with a Grenade Pack enters play by Deep Strike and does not suffer a Deep Strike Mishap, nominate one model in the unit immediately after it arrives. That model can make a single special shooting attack in the Movement phase with the profile below - this represents the unit's Grenade Pack attack. A unit that fires Grenade Packs in the movement phase can still shoot in the subsequent Shooting phase; however, it must target the same target unit if possible.
