I finally found a site where someone's gotten screencaps of the MACO insignia. Apparently, the upper patch on the right sleeve is standard for all MACOs, the upper patch on the left sleeve is the specific unit patch (here for the Enterprise squad), the lower patch on the left sleeve is name, and the lower patch on the right sleeve is rank. The ranks are taken directly from US Army rank insignia. So Army/Navy? Army-Navy/NASA? I don't know.

Technically... the Klingons and Romulans aren't intergalactic enemies. Interglactic means between galaxies. Interstellar enemies, yes. To pick apart one's grammar.

perhaps it was meant to be intragalactic

I think the word "intergalactic" has become one where the meaning isn't quite exact (there are many others, most notably "literally"). It's used to mean "in outer space."

I agree, nelamm

In a world where people repeatedly confuse astronomy and astrology, it's no wonder that intergalactic simply means 'out there'.

Not to mention that Trek itself has made the mistake many times.

cleo, when exactly did Star Trek fall in the 'intergalactic' trap? I love to nitpick these things and I never noticed that one.

ETA: Let's take this to Star Fleet 101 instead.
