Tarantula Sentry Battery

This unit has the following abilities: And They Shall Know No Fear, Bolter Discipline, Shock Assault and Combat Doctrines.

When this model is destroyed, roll one D6 before removing it from play. On a 6 it explodes and each unit within 3" suffers 1 mortal wound. 

If every unit from your army (excluding UNALIGNED untis) has the BLOOD ANGELS keyword, then every unit that has the Combat Doctrines ability and is in a BLOOD ANGELS Detachment gains the Savage Echoes ability, below.

Whilst the Assault Doctrine is active, if a unit with this ability makes a charge move, is charged or performs a Heroic Intervention, add 1 to the Attacks characteristic of models in that unit until the end of the turn (note that this is cumulative with the bonus these models receive from the Shock Assault ability).

When resolving an attack made with a melee weapon by a model with this ability in a turn in which that model’s unit made a charge move, was charged or performed a Heroic Intervention, add 1 to the wound roll. When a unit with this ability Advances or makes a charge move, add 1 to the Advance roll or charge roll.
