Sure thing, Mike can be on the same train/elevator as Israfil.  So in case I didn't make it clear, the train is actually an elevator that takes passengers from the planet surface up to the spaceport which is like a space-station, but it is tethered to the planet by the space elevator.  The spaceport is like an airport, where people board shuttles that take them to other orbital, untethered space stations, or to fleets in orbit.

As for ranks, I am using the following [url=http://www.militaryfactory.com/ranks/navy_ranks.asp]link[/url].  Changes I am making are that for combatants and command posts, we will go from Ensign to Fleet Admiral, whereas for non-combatants like Mike, we will go from Seaman to Master Chief Petty Officer of the Navy.  If Mike's just starting out, make him a Seaman, if he has some experience under his belt, you can make him a Petty Officer 3rd Class (PO3).
