A minor note---
Interesting...Garrovick was wearing the green tunic in the first three acts and then switched to the gold tunic in Act IV.
I don't recall Kirk having done that in TOS.
I was never a fan of the green one in the first place.
Kirk wore his green wrap at the beginning of "Court Martial:"
...and then his regular gold tunic later in the episode:
And he did it in "Charlie X" when he stepped into the turbolift in his gold velour and came out onto the bridge wearing his army green wool-knit wrap.
