See, the problem is that all your arguments revolve around the same thing, you guess, maybe, grenades wouldn't make it any worse. Then you extrapolate all kinds of limitations based on your guess. It's becoming increasingly apparent as you keep moving the goalposts that everything comes down to your guess and your assumptions because there's never enough evidence for your guess.
And it is notable that in these battles in the corridors, you don't see many vaporizations going on, almost as if they're using lower power settings to avoid blowing up the ship.
First off, the stun grenade that you yourself pointed out do zero damage to the ship and would be totally usable, as would anything else designed to be lethal or debilitating that won't break through the metal equipment covers lining (which are fairly thick, I think at least a quarter inch).
Secondly, and I'll have to get out my copy of the TM and look for a cutaway to confirm, but I don't think and can't find a reference to there being anything particular dangerous in the walls, I know there's some computer wring in there and voyager has some gel packs in there sometimes, but all the vital stuff is deeper inside, in the Jeffries tubes.
You assume... but you'd assume the same thing about exploding consoles, wouldn't you?
The exploding bridge consoles are also mostly a cheap tool for drama, yes.
The Defiant came under fire from Jem'Hadar forces while unloading and retreated. You assume they had time to unload everything and you assume people would specifically complain about grenades onscreen but that's just your assumption, as with most of the arguments here.
The latter is an assumption, but a reasonable one in light of how the ground troops were written otherwise.
The former is not an assumption, it's what they said in the episode:
QUARK: Nog, shouldn't you be helping Doctor Bashir unload the supplies?
NOG: We're pretty much finished.
Now, "pretty much finished" is not "finished", but there were several more scenes before the defiant had to bail, and transporters are very, very fast, Voyager once beamed up the entire crew of a Klingon ship, a crew of hundreds of people, in seconds. With, being generous here and assuming no more than a few minutes between this point and the defiant leaving, it's not plausible that they still had stuff left unloaded.
is a great example of why your assumptions are so specious. We see 19th century US marines with bayonets, and modern marines are issued knives. But according to the same reasoning you've used here, because we mostly see marines shooting people today, you assume they must not possess knives nor have a doctrine about when to use knives. We can see a few cases of marines stabbing a bitch, but even then you assume marines don't use knives because it's so rare compared to marines shooting a bitch and there just aren't enough instances of stabbing to get past your assumptions.
A moment's thought reveals the obvious fallacies there. It's exactly the same for the Federation.
I think you're being a bit uncharitable here and misreading my argument. I did not say "you're just assuming marines still have bayonets, we don't see them using them very much so they must not". I'm fully aware the marines still have knives and those knives can be used as bayonets (I'm fuzzy on if they still actually do bayonets drill, I think someone stopped doing it lately but I don't recall who).
What I
said was "a hundred plus years ago, they used to have this one particular kind of bayonet:
It is now a hundred years later, we've never seen one them with one of those, it's not reasonable to assume that just because they had this one specific weapon at some point they must still have it on hand now."
Do you have any quote or proof it was Bajoran beyond "I assume it to be so because it would ruin my argument otherwise?"
Actually I did have a quote, but I misread the transcript and thought it was thrown at the federation officers and not by them. My bad.
TNG Q-Who, Riker gouges a crater that looks to be half as deep as Worf's knee and also about half his height wide out of solid stone. Note, that's a type 1, the smallest and weakest phaser of all.
The issue is, these are phasers, being directed against rock. Phasers are notoriously material dependent, because they're not just simple thermal weapons, they do weird stuff (like the famous disintegration effect, which is not possible via normal thermal effects).
I say this because phasers behave very differently when it comes to metal, they don't vaporize big chunks of it, they cut through it:
This is seen not just in Too Short a Season, but in "Aquiel" and "Who mourns for Morn" where quark jumps into a metal crate and a beam og some kind punchs right through one side and out the other (and Morn is the only time we see this happen fast, otherwise it's about as fast as a cutting toarch)
This is relevant to the anti-tank issue because, as I said before, you cannot kill a tank by just slowly poking a few holes in it, modern anti tank weapons have secondary effects related to how they make those holes that will destroy the interiorcof the tank or kill the crew. Phasers do not, a Scorpion tank with a hole in it is still just as deadly, and cutting that hole is a slow process as the federation trooper cuts through inch after inch of armor while highlighting his position with a bright orange beam. Bad idea.
Disabling a scorpion in this manner is still possible, but it will be very hard, because even if the federation soldier knows where to aim (which isn't hard to figure out, tricorders and so on), Scorpions are built to be resilient and redundant so any attempt to disable one will require multiple hits (engine, ammo/gun, coax ammo/gun, and two crewman), which the Scorpion can easily disrupt by, say, movingly slightly.
In TNG Chain Of Command we see a type 2, the phaser pistol which is slightly larger, vaporize a large tunnel through solid rock. In the dialogue, Worf states that this is phaser setting 16, and the tunnel he's digging will go through 75 meters of rock to a lava tube.
That's a common misunderstanding of that scene, look at the actual dislogue a bit closer:
PICARD: There's a lava tube beyond here that runs for seventy five metres, then it connects with another chamber. We need to get through here. This tube opens up beyond this crack. We could widen the opening, then we should be able to crawl through. Mister Worf.
There's already a 75 meter long tunnel in the rock, they only have to destroy a thin layer of rock blocking it in order to to get through to it (it's worth noting when the Delta Flyer once got buried underground to a similar depth, Voyager had to beam down special phaser drills in order to dig it out, handheld phasers were not up to the task).
DS9 Way of the Warrior, Sisko and Kira use widebeam sweeps to clear an entire room in seconds.
I'm aware widebeam mode exists. It's seemingly incapable of operating even on the "kill" function, let alone the "melt battle tank" mode.
