Mines: How do they work?

[Cyrien]

Mine damage isn't dealt in combat. It just happens to the ships that hit them.

I have never had combat in a sector that had mines leftover so I don't know if they appear in tactical combat, but I don't think they do. I think if you have a fleet/satellites/starbase in the same space as mines then the ships entering take damage from mines first then any survivors enter into combat with the ships there.
