hold down shift and then right click from one unit to the next in the order that you'd like to destroy them. I'm 99% sure it's shift. It may be ctrl.

So with all of my units selected, I hold down shift and I manually click -each- ship I want destroyed next?

Thank you very much. This helps so much.

Sorry again, but I see shift ques up -one- more target, but is there another key that selects a target of all the same type instead of manually shift and selecting my next targets. Example: I want fighters to attack all of the LRMs in the well. Do I have to shift and select each one of the enemy ships, or can I press a different key and it targets all of the enemy ships of that type.
