Ask any fic writer who has dabbled in Star Wars military fiction and they’ll tell you they have pulled their hair out trying to find out just how the rank system works between various military factions. Thankfully for all of us, Jason Fry and Paul Urquhart managed to answer some of those questions definitively in EG to Warfare.

I’d have liked to have done something with the unit formations, which real soldiers tell me are unrealistic, but I subtly hinted that the Kaminoans are a bit unrealistic and childlike in their liking for neat, obedient ranks of expendable troops.
