Impulsor

This ability always takes the form **Deadly Demise X**. Each time a model in this unit is **destroyed**, after the units embarked within it (if any) have made their **emergency disembark moves**, roll one D6. On a 6, that model suffers a **deadly demise**; each unit within 6" of that model suffers a number of **mortal wounds** denoted by **X** (if this is a random number, roll separately for each unit within 6"). 
***Example:** An Impulsor with a unit of Intercessors embarked within it is **destroyed** by ranged attacks. First, any unresolved attacks made by the attacking unit are resolved. Then the Intercessors make an **emergency disembark move**. Then the roll is made for the **Deadly Demise** ability, and on a 6, that ability is resolved. Finally, the Impulsor is removed from the battlefield.*

This ability always takes the form **Firing Deck X**. In your Shooting phase, each time this **TRANSPORT** is **selected to shoot**, if one or more units are embarked within it, resolve the following sequence: 
1. Select up to **X** models embarked within this **TRANSPORT** (excluding models whose units have already been **selected to shoot** this phase). 
2. For each selected model, select one of its ranged weapons (excluding **[ONE SHOT]** weapons). 
3. Until this **TRANSPORT** has resolved all of its attacks, it has all of those selected weapons in addition to its other weapons. 
4. Until the end of the turn, units embarked within this **TRANSPORT** are not eligible to shoot. 

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 If a rule make a Combat Doctrine active for a unit, any Combat Doctrine previously active for that unit is no longer active for that unit.
