This is how you get all your officers killed in the battlefield.

Colonial sharpshooters were already excellent at picking off Redcoat officers in 1774.

Then both Union and Confederate officers were picked off at a high rate. Look at how garish Grant’s uniform is compared to Stormin’ Norman.

Finally we learned. WW2 officers had ornamentations removed or covered, even far from the battlefield. When the Indianapolis was hit, no one could locate Admiral Spruance. They thought he might have died. Nope, there was a guy wearing just khakis and no ornamentation helping fight the fires— turned out it was Spruance. No one recognized him because he only recently transferred his flag over.

Why do militaries have such a respect fetish anyway?

So you're saying every single other Star Trek uniform sucked.

(Although I would argue that rank on the uniform sleeve like in TOS would work for your purposes most of the time.)

I am the opposite.

Its like some symbolism where there rank chokes the person beneath the uniform. Actually makes me feel kinda sick.

There's one STD episode where they're wearing EVA suits and they have light-up Starfleet insignias on the boots.

If it was just the Delta, that would be kind of cool. Very likely would violate the Prime Directive constantly, but...

Maybe it could be for the psychological benefit of the person wearing the uniform? Like, if youve got a post scarcity utopian society where people dont need to work, but youve got some job that needs doing that can be a bit dangerous or tedious at times and therefore might be inherently unattractive to many, like ship's crew, and you cant just pay people a bunch to do it because you've done away with money, one incentive you might have to offer is social status and a sense of personal achievement. In which case, you might use bright flashy displays of rank, because it gives the person that has attained it a bright flashy reminder of "hey look at you, you've achieved this fancy rank that everyone that didnt join the fleet or didnt get as far as you yet doesnt have", and gives any regular civilian that sees you a blatant reminder of "hey, this could be you, if you're willing to put in the work for it"

Maybe the whole uniform is a hologram!

All their stuff is programmable matter, so, probably

Sew? Who sews when they have replicators?

Do you think Garak was really able to stay in business being a plain, simple tailor? And that was 800 years earlier.

You’re the quartermaster and a snarky engineer from 800 years ago is complaining that she likes to wear her jacket open. Do you get into a long drawn out fight you’re probably going to lose, or go, “Right Commander Reno, let me go ahead and replicate the J rank variant for you.”
