Each time you gather attack dice for a **[BLAST]** weapon, add one additional **attack dice** for every five models that were in the target unit in the Select Targets step (rounding down). If this ability takes the form **[BLAST X]**, each time you gather **attack dice** for such a weapon, add **X** additional **attack dice** for every five models that were in the target unit in the Select Targets step (rounding down) instead. 
***Example:** If a **[BLAST 2]** weapon with an **A** characteristic of 3 targets a unit containing 12 models, you would gather four additional **attack dice** for that weapon (for a total of seven for that weapon).*

Units containing one or more models with an **[INDIRECT FIRE]** weapon can shoot using indirect shooting (10.07).

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