In The Cage, all officers wore a single stripe. In WNMHGB, Kirk wore two stripes while the other major characters all wore one; a subtle update from the original pilot that helped to identify the captain.
By the time of TOS proper, the uniform tops had been updated to brighter colors with black collars that we are all familiar with and they had also changed to the much more detailed scheme of wavy stripe +/- broken stripe sleeve braids that separately identified all ranks up to captain, beginning with plain sleeve for ensign. The full pattern existed, whether it was applied accurately is another matter -- but that has been a consistent feature in every era of Trek!
JJ-Trek adapted the classic TOS pattern of solid wavy stripes +/- broken stripes and simplified it to thick +/- thin stripes. The JJ pattern was subsequently re-used for the Enterprise uniforms in DSC S2 (when they finally remembered to include them) and we saw separate insignia for each of captain, commander, lieutenant commander and lieutenant.
SNW Pike is still wearing the specific captain insignia of the thick-thin-thick pattern that he wore in DSC. Alongside this, we have now seen several characters wearing two thick stripes and several wearing one thick + one thin -- so whatever they are doing, it's not a return to the insignia from The Cage or WNMHGB. I actually wonder if someone has mixed up the JJ/DSC pattern of thick/thin stripes with the similar (but different) pattern of contemporary naval stripes.
But I agree, time will tell.![]()
Yes, I agree with your assesment and have notice this as well. Like, M'Benga has two larger stripes, but they are pretty far apart. And then so does Nurse Chapel. Exactly the same. This doesn't make sense if you want to be consistent with canon. Chapel had no stripes during the three years of TOS, making her an Ensign or an non-commissioned officer. Memory Alpha notes, however, that she was raised to the rank of Lieutenant by The Animated Series (TAS).
I should also note, that even though hypotheticaly a Lieutenant, Junior Grade, should be either a dotted line or a one distinctly thinner line, I don't think we have ever actually seen one on screen.
I wonder if the special (and Discovery added) white medical uniform will always have a different two widely larger bars regardless of rank. And when/if those personnel change into science/medical blue, will they have the standard rank insgnia.
At any rate it is inconsistent. I would prefer they simply go with the TOS system, with the upgraded solid bands and not squiggly ones. I have also always wanted Star Trek to consistently have and use a set of enlisted officer rank insgignia for crewman, chiefs, etc.
