Weapons Platforms Usage?

[jars_u]

Mhhh... if in combat sat's are placed randomly around a planet and ships can go around them, how are space stations handled? If you but a battle station in orbit around a planet do attackers first have to destory that and then combat aganist weapons platforms occurs? So weapons platforms can be used both aganist space ships and ground forces? Have not really had the chance to use them yet myself.
