That’s because tactically, it’s incredibly stupid. “You just sit there and do nothing while our incredibly slow spider ships make a web around you.” The only reason is worked is because the Enterprise was prohibited by the Needs Of Plot to remain stationary.
But it was a striking image.
The biggest thing they forgot, and the most useful, was the Genesis Bomb, er…Device. Put one of those in a Borg cube, or a Jem hadar planet, and problem solved.
Lower Decks and Picard both have Genesis devices ‘featured’ in a couple of episodes - not in use - but there and ‘available’ - one of them was the plot of a ploy/scheme of a former cadet.
Recurring members of the crew included Stiles, DuSalle, Rodriguez, Leslie, Osborne, and Hadley. The last gent was seen many times manning the Navigation station instead of Chekov, but he never had a line of his own. However, Scotty did address him by name in “A Piece of the Action”:
Mr Hadley, check the Linguistics banks. Find out what a “heater” is.
Lieutenants Palmer and Lisa substituted for Uhura in “The Doomsday Machine” and “Turnabout Intruder,” respectively.
After I went to bed last night, I realized I forgot Lt. Kyle. He could be found all over the ship.
He even got killed in one episode. Don’t worry, he was better by his next appearance,
I think there must have been a breeding farm dedicated to churning out Redshirt clones.
“That was our last Leslie clone.”
“I was hoping you’d say that.”
Wasn’t there a deFalco, who usually worked in the transporter room?
Now that one is interesting. That actor played a character named Angela in two first season episodes, which aired consecutively but were shot 3 months apart. Angela was in several planetside scenes in Shore Leave and may have had a few lines; she was the one who was getting married to a, ahem, red-shirt at the beginning of Balance of Terror and being comforted by Kirk at the end of it. She was also almost but not quite in Space Seed.
While Angela is somewhat more significant to the plots than a random crew member, it is not altogether obvious that she was meant to be the same person in the same way as Riley, M’Benga and Mudd clearly were. Lisa does not seem to be the same character at all, just the same actor.
“Angela” was played by Barbara Baldavin. She had a long career as an actress (I spotted her in an episode of Columbo recently). In “Turnabout Intruder,” she looked so different from her earlier TOS appearances I must have seen that episode a dozen times before I realized she was the same actress.
Looking at her entry in IMDb, I see she died just a few weeks ago, on 31 March. May she rest in peace. 
One character I wish we had seen again is Tonia Barrows, McCoy’s one-off love interest in “Shore Leave.” She was gorgeous!
Played by Emily Banks, an actress and a model. 
Also:
Freeman, aka “security chief” (3 episodes)
Arguably Mallory or Jackson. Two Enterprise crewmen played by the same actor, who also played unnamed crewmen in a few other episodes.
Galloway aka guard/ security chief. (8 episodes)
Kelowitz (3 episodes)
Fields (4 episodes)
Farrell (3 episodes)
there may be others
Freeman was created by screenwriter David Gerrold to be a cameo for himself in “The Trouble with Tribbles.” Producer Gene Coon nixed the idea, saying that Gerrold was too skinny to play a Starfleet crewman.
Mallory and Jackson were obviously clones from the abovementioned breeding farm.
I think that the fact that the two named appearances were different names argues against any of the appearances being the “same character”. The case would be stronger for a repeat-actor who’s only named once.
You misunderstand. The actor played unnamed crewmen in various episodes. They might, arguably, be Mallory, or they might be Jackson.
No, that’s it entirely. If the actor’s role were only named once, then we could parsimoniously assume that all appearances by that same actor were the same character. But since he was named twice, with two different names, we absolutely cannot assume that, and once that precedent is set, it’s just as reasonable to suppose that he played five different characters as it is to suppose that he played exactly two.
This is why my advice to new actors is, always make sure your character has a name. Even if it is never said, as long as th script shows it. That way you don’t end up in imdb as “second woman” or “crewman”.
Just make sure the name isn’t “Guy”!
This thread reminds me of the farm planet, and the plants with spores that cured diseases and made even Spock happy. A crewman smuggling the plants aboard ship to study them, or be a drug dealer, could’ve been a plot. Except for not wanting to go back to work, what was the downside to those spores anyway?
Not at all. Paul Baxley played “Freeman” in two episodes, and “Security Chief” in another. Memory Alpha treats them as the same character. But Baxley also played several other minor roles, including Black Knight, Policeman, and Defiant Captain. I think we can safely say that Freeman wasn’t promoted from ensign to Captain in two years. I have no problem with thinking that Security Shief was the same character as Freeman, while Defiant Captain was a different one.
I happened upon this very funny song today , and decided to read this thread to see if it resonates well (it’s a bit of a stretch, but what the hell. Please enjoy The U.S.S. Make Shit Up).
“This one has a smashing ass and a lovely set of tits!” 
Here is a Treksong I was taught at an SCA event back in 1976, insofar as I remember it (well, it was almost fifty years ago…):
STARFLEET (sung to the tune of CW McCall’s “Convoy”)
It was Stardate 3216.9, and we’d swung the phasers 'round,
I said “Scotty, this here’s Captain Kirk, and I’m about to put the hammer down.”
We were sailin’ through interstellar space, about 90 times the speed of light.
We met a cave full of Klingon Smokey Bears, and we passed 'em on the right.
They said “Hold on, Federation Roger Ramjet, the limit here’s Factor 3!”
I said “Uhura, did you hear Smokey ask if he could open a hailin’ frequency?”
CHORUS:
‘Cause we got ourselves a Starfleet, trekkin’ through the night!
Yes, we got ourselves a Starfleet, ain’t she a beautiful sight?
Come on and join our Starfleet, ain’t nothin’ gonna get in our way!
We’re gonna take our mighty Starfleet across the Milky Way!
Starfleet! Starfleet!
We were half a parsec front door to back, and a light year edge to edge,
and we showed them Klingon Smokey Bears how far the Treaty’d stretch.
We had cargo liners, cruisers, scouts! We had dreadnoughts fore and aft!
And sixteen long-eared Vulcan hippies in a rented shuttlecraft!
Pssht Uh. put those Vulcans in behind the cargo liner. His computer’s gone out.
CHORUS
Well, we’d just come out of Klingon space, and what should lie ahead
but a Romulan border checkpoint, and my phaser banks were dead!
I said “Scotty, this here’s Captain Kirk, I don’t believe I can read that sign!”
So we shot the gate at Warp Factor 8, and we left 'em all behind!
CHORUS
Pssht Uh, ten-four, Good Buddy. Keep the matter side in, and the anti-matter side out!
