Re: Scotty and his military comment
You can have a fleet of merchant vessels. "Fleet" is not exclusive to military collections of ships in a navy.
True. However, it was established (in the Prime universe/timeline/reality thingy, at least) that there also
exists a "merchant service" which is separate from Starfleet - one which will accept personnel who have been dropped from the Academy for failing a fifth-year psycho-simulator test.
Let me never fall into the vulgar mistake of dreaming
that I am persecuted whenever I am contradicted.
