Nightwind: you did, but it isn't the trek ones... just remembered that I went through the auction photos from the "It's a Wrap!" auction...
Classic trek, we don't see enlisted - at least, not identified as such. We do see engineering and command personell in a jumpsuit.
Early TOS (The Cage) we DO see enlisted - officers have a single stripe, captains two (we see two of them in the Cage). Chiefs have hollow filigree stripes looking something like:
–––––––––––––––––––––––––
/ / / / / / / / / / / / /
–––––––––––––––––––––––––
I think there are some in gold and some in silver; if I'm right, this is two grades of NCO, probably PO and CPO
But in the TOS Movies, oh, do we see enlisted!
In The Motion[less] Picture...
Chiefs have a square
Petty Officers have a triangle
Specialists have a slash
Crewman have no insignia
And in the later ones...
Specialist has a diamond; Sp2 has smooth, SP1 has texture in the corners
Petty Officer an octogon; PO2 has smooth, PO1 has texture in the corners
Chief Petty Officer has an octagon with tuft on the top
Senior Chief PO has has octagon with gold bar in the middle, and tuft on the top.
Master Chief PO 2d class has a circle with a gold textured diamond in the center
Master Chief PO 1st Class has the same as 2nd, plus the tuft
So... Filling it out for Trek
E1 (presumed) Recruit
E2 Specialist 2C
E3 Specialist 1C
E4 Petty Officer 2C
E5 Petty Officer 1C
E6 Chief Petty Officer
E7 Senior Chief Petty Officer
E8 Master Chief Petty Officer 2C
E9 Master Chief Petty Officer 1C
And I'll note also: Paramount DID make rank insignia we never saw onscreen. They didn't make a fleet captain insignia... but DID use the rank onscreen (The Menagerie).
I need to update my ranks essays on my website.
