Dah! It is very rarely when Japanese animators do actual insignias, unless the insignias somewhat played a role in a story. The absence of insignias just underlines two things, the animators can use recycled footage, saves a lot of time and money ( did u ever wonder y in whole movies/series the characters never change clothes (wow, it should be stink out in real world without laundry
), and after all, for some reason (unknown to me, maybe magic
), the heroes miraculously, with out any rank insignias, know the rank and status of the person, even if our heroes never seen him/her before!

PS: Interesting note, even Orb played somewhat role in the Gundam SEED, only in part 2, Destiny with much bigger shoes to fill, they, finally, got real rank insignias, not the imitation (Japanese animators often pretend that there rank insignias, just like in Yugen Ordian, the North American Empire (the US) , but up close there no actual rank).
