And then, thinking back to my previous series... I have tons and tons of ranks.
Electron ranks go from electrokinetic->Lightning/Kinetic-Lightning->Elika->Namika->Nuclearkinetic (Each of these ranks can take "minor" or "arch" eg Minor-Elika or Arch-Namika).
Proton ranks Deputy->Sheriff->Lieutenant->General->Telika.
Telepaths rank themselves with a number representing how far they can reach + a division (projection / empathy / biopathy / placing / etc)
and there are many many more.
And I'm thinking about Book 6 and less than 10% of my ranks appear. The only ranks you see in book 6 are the ranks that matter to the characters. For example, [S t r a d i n] is technically a Minor Namika, but J calls him Namika. It's not relevant to her which kind he is because as far as she's concerned, he has all the properties of a normal Namika. She never refers to [K w a n] by her telepathic designation of "projection rank i". The term never appears in books 5 or 6. It exists in the story, but it's never so critical that J needs to mention it.
ok... back to yours. I ask of you... how important are the ranks? Which do you really *need*? Of course in a first draft use "lieutenant corporal". But in a second draft, maybe that guy is just a lieutenant or just a corporal. In a 3rd draft, maybe he's just "a leader baddie who wants to beat up the good guys".
Ideally the ranks are so unobtrusive that the story can remain dominant.
Here are some random questions to demonstrate what I mean:
a) In Seabrass's story, Tammon's rank/title is "Cityseer". Can you name the rank of Mawk?
b) Before the term "battle droid" was coined in 1990, how many classes of droid did Star Wars have?
c) Aside from "Prime" name at least 3 ranks of autobot.
(okay (c) is me cheating)
d) Aside from "dinobot" and "triple changer" name 3 classes of autobot.
PS: Classiarii and legionarii didn't throw me. I mentally re-assign them as "military guy carrying gun". Therefore no complaint. A 3rd, 4th, and 5th group merely joins this existing classification. Again, no complaint. UNLESS all five are in the same paragraph.
