[@Sep]Awesome, thanks! So in the case of a police chief it would be non-military right? He is basically a civilian, but answers to the Admiral (as top of the hierchy) simply because he is the leader around here and the security chief because he's the obvious choice next in line, he won't actually have a rank and stuff. 
I wanted to add some of the boarding in my introduction post and wanted to describe his bio in the form of a conversation with his recruiter, hence the questions. Starting now I will be working full-time on the character sheet, so I hope to complete it soon!
