So, my first question is this:
Do all 4 layers occur simultaneously, or is the winning of one the gateway to entering the other?
For example:
Team A holds Planet X. That is to say they are in control of the surface, the air and near orbit space. Team B wants to take Planet X from Team A's control. Must Team B win some sort of victory or create some kind of foothold in near orbit space before they can launch troops and arament to the surface? Or do all three layers happen simultaneously? Must Team B control strategic space near the planet before they can even begin the other? What does a "front" look like in space based warfare?
I think there's a temptation in Science Fiction/Space Fantasy to transpose Earth based warfare one-to-one to space, and it doesn't seem to really work very well.
