You can re-roll failed Morale tests for this unit.

When this unit fires any ranged weapons from the following list, you can choose for it to fire special ammunition. If you do so, the Bolter Discipline ability does not apply when resolving their shots, but you instead choose one kind of ammunition from the table to the right and apply the corresponding modifier. 

(absolver bolt pistol, auto bolt rifle, bolt carbine, bolt pistol(and heavy), boltgun(and combi), bolt rifle twin boltgun, stalker pattern boltgun/rifle, storm bolter, hellfire extremis(boltgun profile), all master crafted bolt weapons or a guardian spear) Table: Dragonfire Bolt, Hellfire Round, Kraken Bolt, Vengeance Round

If this unit makes a charge move, is charged or performs a Heroic Intervention, add 1 to the Attacks characteristic of models in this unit until the end of the turn.

All ADEPTUS ASTARTES and HERETIC ASTARTES models gain this ability. Instead of following the normal rules for Rapid Fire weapons, Rapid Fire bolt weapons used by models with this ability make double the number of attacks if any of the following conditions apply: 1) The firing model's target is within half the weapon's maximum range. 2)    The firing model is INFANTRY and every model in its unit remained stationary in your previous Movement phase. 3) The firing model is a TERMINATOR, BIKER, CENTURION, or DREADNOUGHT. For the purposes of this ability a Rapid Fire Bolt weapon is any weapon with the Rapid Fire type whose name includes the word 'bolt' (e.g. boltgun, bolt rifle, storm bolter, combi-bolter, hurricane bolter, inferno boltgun, etc.) This also applies when firing the boltgun profile of a combi-weapon (including the bolt weapon profile of Relics such as Blood Song and the Lion's Wrath) and when firing relics that replace a Rapid Fire bolt weapon, so long as the relic is also a rapid-fire weapon (e.g. Primarch's Wrath, Fury of Deimos, etc) The gauntlets of ultramar and the Talon of Horus are also considered Rapid Fire Bolt weapons, as is the guardian spear used by Deathwatch Watch Masters.
