Troops with a high BS have a To Hit score of 1, 0 or even a negative number (as shown above). If shooting modifiers result in a required score of 1 or less, the model has an increased change to hit the target. If the model first rolls a 1 to Hit, they may re-roll the result as shown on the chart below:
Ballistic Skill | Requirement to Hit on Re-roll |
6 | 6 |
7 | 5+ |
8 | 4+ |
9 | 3+ |
10 | 2+ |
