The subject of rank came up in a PM, and it's one worth repeating here too. 
I'm going to suggest that DefCom squadrons like Wylde Fyre, that have dual-role flight and ground personnel, and likely DefCom ground forces as well as they're dependent on the Naval forces, use US Marine Corps-style ranks. 

As all of our characters are flying personnel, we'd all likely be officers. Erien's rank, as commander of the squadron, will be set at Colonel. I'll choose people to fill in as 2IC and other appropriate ranks as more characters go up, and we get into the game a bit more, based on their attitude and service record, as well as their age and other factors.
