Does the Sabine crew work for any bomb? That's huge.
Sabine crew: any bomb dropped by a friendly?
Yes. Any friendly bomb.
It's a little weirdly worded though; it implies that it's not optional, but if you have multiple bombs you can choose between them.
It probably ought to have had a 'you may' in there somewhere.
And yes it is huge. I ran her yesterday for the forst time, and that 1 extra damage cost my opponent his first TIE Fighter as I dropped a proximity mine on him.
Like thespaceinvader said, the wording implies it is not optional, so better use it on a bomb you are sure will have a target within range 1.
