Per the new rule, you actually have to send a SF/AUX into the same grid as the CSP in order to engage it.
Capital Ships cannot engage CSP by shooting at them, like I did in my last post.
Other SF/AUX cannot engage CSP by shooting from a distance. They actually have to enter the grid. Although, if you simply wait one round, those SF on CSP will blow up, so it's more of a timing thing.
If you're not in a hurry, you can wittle down CSP from a distance. If you are in a hurry, then you need to send in the dogs if you want to do a massive bombing run.
