I'm sure this question has been asked before, but I don't have the time to browse through all previous topics.
so... if I put, let's say, a mk III logistic command station on a planet with a gravity drill, will the effect stack? Will my own ships move a bit faster and enemy ships even slower? Or is that difference so small that it's just a waste of the logistic cc? a military cc right next to the gravity drill might be the best solution to deal with enemies, but I figured I'd just ask anyway.
