At one point, I thought the department-colored coveralls were enlisted uniforms, but we saw officers (such as Lieutenant Kyle) wearing them too.
Correct me if I'm wrong, but the only time Mr Kyle wore a jumpsuit was Mirror Mirror. So likely Kyle is an officer in the Prime Universe, but enlisted in the MU.
Of course, then there's Mr Leslie who did wear both uniforms in the Prime Universe. Of course, Leslie wore different uniform colours, was referred to by several names, worked at least three different departments, frequently canged his rank stripes between Ensign and Lieutenant, and even continued eporting for duty after being killed, so maybe he isn't the best precedent to cite.
The guy who designed WOK uniforms new what he was doing.
One uniform for officers and another for ratings, clear insignia for petty officers etc and clear insignia for officers.
Also white for command, yellow for engineering, grey for science, light green for medical, dark green for security, light blue for services and red for officer cadets and trainee ratings.
Just a pity nobody seemed to follow his notes when doing manuals or later movies.
I love TWOK's uniforms, they are probably among the coolest in all Trek. But they are confusing as hell. As big a Trek nerd as I am, I've never been able to figure out the department colours beyond white for command and red for cadets, and the only rank insignia I can identify are the ones for Captain and Admiral. I'm glad Trek eventually reverted to a simpler division colour code and simpler rank identification.
Even Trek XI tries to dance around the issue by having Pike describe Starfleet as a "humanitarian peacekeeping armada."
Not quite, Captain Pike actually described the
Federation with those terms, which is a little scary.
Pike: "You understand what the Federation is, don't you? It's important. It's a peacekeeping and humanitarian armada."
Not the first time Star Trek has sloppily referred to Starfleet and the Ferderation as one and the same, and probably won't be the last.
I took that to mean that Starfleet was like the Israeli and Canadian military, where there are internal divisions for things like the navy, the army, so forth. But without there being completely separate branches. The forces are integrated.
Although essentially correct, it's a bit more complicated than that. Canada does have seperate rank structures for its Army, Navy and Air Force. But yes, the entire military is considered one whole organization, with there being only one actual chief of staff.
