Chief Librarian Tigurius

Before the battle, in the Muster Armies step, for each leader and support unit in your army, you can select one friendly bodyguard unit that unit can lead. That unit will then lead that bodyguard unit for the battle and form an attached unit with it. Unless otherwise stated, each bodyguard unit can only have one leader unit and one support unit attached to it.

At the start of your Command phase, you can select one Combat Doctrine listed below. If you do, that Combat Doctrine is active for friendly ADEPTUS ASTARTES units with this ability until the start of your next Command Phase


Assault Doctrine
When this unit is selected to make an Advance move, that Advance move does not prevent this unit from being eligible to declare a charge. 


Devastator Doctrine
This unit's ranged attacks have [ASSAULT]


Tactical Doctrine
When this unit is selected to make a Fall-back move, that Fall-back move does not prevent this unit from being eligible to shoot and eligible to declare a charge. 


Unless otherwise stated. 
- You can only select each Combat Doctrine once per battle
- Only one Combat Doctrine can be active for each unit. If a rule make a Combat Doctrine active for a unit, any Combat Doctrine previously active for that unit is no longer active for that unit. 

At the start of the battle round, if a model with this ability is your WARLORD, gain 1 CP

Adeptus Astartes Psyker units with this ability have a psyker level of 1 of higher, specified in that unit's abilities. Each Psychic ability has a psychic level of 1 or higher, specified in that ability's name. 


In a battle round, a friendly ADEPTUS ASTARTES PSYKER unit can use a number of psychic abilities whose total psychic level does not exceed that PSYKER unit's psyker level
