Twin heavy bolter

This ability always takes the form **[SUSTAINED HITS X]**. Each time an attack made with a **[SUSTAINED HITS]** weapon results in a **critical hit**, that attack results in a number of additional hits on the target as denoted by **X**.
***Example: An attack made with a **[SUSTAINED HITS 2]** weapon results in a **critical hit**. That attack therefore hits the target three times (once from the **critical hit**, and twice more from the **[SUSTAINED HITS 2]** ability).

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

This ability always takes the form **[RAPID FIRE X]**. Each time you gather **attack dice** for a **[RAPID FIRE]** weapon, add **X** additional **attack dice** if the target unit was within half range of that weapon in the Select Targets step. 
***Example:** If a **[RAPID FIRE 1]** weapon with an **A** characteristic of 1 targets a unit that is within half range, you would gather one additional **attack dice** for that weapon (for a total of two for that weapon).*
