Twin burst cannon

Each time an attack is made with a **[TWIN-LINKED]** weapon, you can re-roll the **wound roll**.

In your Shooting phase, each time an attack is made with a **[HEAVY]** weapon, add 1 to the **hit roll** if all of the following apply to the attacking unit: 
- That unit is **unengaged**. 
- That unit was not set up on the battlefield this turn. 
- No model in that unit has moved more than 3" this turn.
