If your Army Faction is HERETIC ASTARTES, each time a unit with this ability is selected to shoot or fight, it can make a Dark Pact. If it does, it must first take a Leadership test before any effects of the Dark Pact are resolved; if that test is failed, that unit suffers D3 mortal wounds. Then, select one of the following abilities for that unit’s weapons to gain until the end of the phase:
■ [LETHAL HITS]
■ [SUSTAINED HITS 1]

Leader

While a Bodyguard unit contains a Leader, it is known as an Attached unit and, with the exception of rules that are triggered when units are destroyed (pg 12), it is treated as a single unit for all rules purposes. Each time an attack targets an Attached unit, until the attacking unit has resolved all of its attacks, you must use the Toughness characteristic of the Bodyguard models in that unit, even if a Leader in that unit has a different Toughness characteristic. Each time an attack successfully wounds an Attached unit, that attack cannot be allocated to a Character model in that unit, even if that Character model has lost one or more wounds or has already had attacks allocated to it this phase. As soon as the last Bodyguard model in an Attached unit has been destroyed, any attacks made against that unit that have yet to be allocated can then be allocated to Character models in that unit.

Each time the last model in a Bodyguard unit is destroyed, each CHARACTER unit that is part of that Attached unit becomes a separate unit, with its original Starting Strength. If this happens as the result of an attack, they become separate units after the attacking unit has resolved all of its attacks. 

Each time the last model in a CHARACTER unit that is attached to a Bodyguard unit is destroyed and there is not another CHARACTER unit attached, that Attached unit’s Bodyguard unit becomes a separate unit, with its original Starting Strength. If this happens as the result of an attack, they become separate units after the attacking unit has resolved all of its attacks. 

Each time a unit that is part of an Attached unit is destroyed, it does not have the keywords of any other units that make up that Attached unit (unless it has those keywords on its own datasheet) for the purposes of any rules that would be triggered when that unit is destroyed.

Abilities
Corrupt Machine Spirits: Once per turn, at the start of your opponent’s Shooting phase, select one enemy VEHICLE unit within 12" of and visible to one or more models from your army with this ability. That unit must take a Leadership test: if that test is passed, until the end of the phase, each time a model in that unit makes an attack, subtract 1 from the Hit roll; if that test is failed, that unit is not eligible to shoot this phase.
Spirit Thief: At the start of your Shooting phase, select one enemy VEHICLE unit within 12" of this model. Until the end of the phase, each time a friendly HERETIC ASTARTES model makes an attack that targets that unit, re-roll a Wound roll of 1.
Invulnerable Save: This model has a 5+ invulnerable save.
