[quote]@Ex, go ahead and write a Codex entry for the Oakridge Military Academy Rank Structure.[/quote]

So based on what you've said, I'll say Oakridge probably don't have non-commissioned personnel (enlisted; think foot soldiers, airmen, etc.), only civilian employees, ranked officers, and cadets (students). I've based this rank concept on West Point/US Naval Academy internal ranking system. 

While they are studying at the Academy, students would hold the rank of Cadet. Cadets would then be separated into class based on year (fourth class = freshman, third class = sophomore, and so on). In school, cadets would be organized into a school-wide Cadet Brigade, which has its own organizational structure. We don't need to worry about that now, but our characters would all have been in one company together (dunno who would have lead it). 

After graduation, ranks would likely be determined using something similar to a traditional commissioned officer system. I've made it a little simpler, since it's not a full-military organization and it's not as large as one would be, but here's what I'd suggest:

Second Lieutenant - most students graduate and begin at this rank. 
First Lieutenant - most graduates are promoted to this rank after a couple years of service. WARG officers begin at this rank.
Captain - graduates given command assignments begin at this rank (i. e., Olivia). 

The rest of the ranks would be determined based on position/duties, time served, and performance, and are as follows: 

Major
Lieutenant Colonel
Colonel
Field-Marshal
Major-General
General

So all of our characters would be first lieutenants, except for Olivia, who would be a captain.

That makes sense - the thing I felt was less reasonable was what I read as a suggestion that WARG officers should be worried about calling in support for that reason. It's not their job to deal with those headaches, IMO, it's their job to survive and accomplish the objectives.
