Marco, yes in SE3 you can put an unarmed escort in each sector around your side, to prevent forward retreat by any survivors of the defense. Or, you can just defend the far side, and not have to.

dmm, for #1, SJ is right. For #2, in SE3 there are no satellites and fighters can deploy strategically - as for mines I don't know - I expect the minefields would have to be detected for them to block retreat, but haven't tested it.

Personally, I tend to think that defending the far side is good enough, and having a chance to break through defenses set up on their own side is more interesting than it is any sort of problem.
