After a lot of trial and error, I think I finally hit on a New Republic Rank Device design that makes sense, still has the "in universe" feel and style and is very different from the ones that I designed for the New Republic Navy Officers and the Imperial Navy.
They are, from left to right, top to bottom:
E-1 Ablesman Recruit, E-2 Ablesman Apprentice, E-3 Ablesman
E-4 Petty Officer 3rd Class, E-5 Petty Officer 2nd Class
E-6 Petty Officer 1st Class
E-7 Chief Petty Officer
E-8 Senior Chief Petty Officer
E-9 Master Chief Petty Officer
E-10 High Chief Petty Officer
Any comments or critiques are, as always more than welcome and appreciated! The final chart should be done very quickly! Please enjoy!
