It doesn't say "
Quote:
they suffer D3 automatic strength 6 hits".
It says
Code:
they suffer D3 Strength 6 hits
, it cannot be automatic and Strength 6, it is Strength 6. The swoop attack therefore targets the enemy formation's defence. For example, if the enemy formation is defence 7, you would need 5s to hit.
However, before you do this you need to roll a D3, which will tell you how many Strength 6 hits the enemy will take, eg a roll of a 1 means that the enemy will suffer 1 Strength 6 hit. After which you would then roll 1 D6 against the enemy at strength 6.
Does that help?
