That purpose is to hide the brutality of war, from either the writer, or the reader.
In either case, allowing to hide the brutality makes it arguably more palatable to commit it (writer) or legitimize it (reader), and therefore contributes to it.
I can’t put numbers on this, obviously, because nobody can. But just denying the argument with a sort of its-not-guns-that-kill-it’s-people-argument is intellectually dishonest.
If you insist that “dropping” is for some reason preferable to “demolish” or “collapse”, say because it’s shorter or the military has trouble spelling those actual terms, I am sure you can find me a reference in non-lethal industries involved in the destruction of construction using the term. My superficial research seems to indicate that those wielding wrecking balls instead of laser-guided missiles see no need to obfuscate their doings.

> Controlled Demolition Incorporated’s team was able to complete asbestos abatement/environmental remediation, prepare the structure for implosion and drop the massive structural steel building just 2 weeks
> Controlled Demolition Incorporated's DREXS (Directional Remote Explosive Severance) System sequentially severed the 4 inch thick flanges of the buildings' support columns to drop the structure without damage to a Boston Fire Department facility just 30 feet away.
Edit: to be clear, I’m against the pedantry at play here. Subject matter experts talk in their specific jargon. We do it in tech, why would the military be any different?
Second, "drop" may be colloquial but I don't see how it's disguising the action and the consequences. It seems to me there are similar objections to "demolish" - it's like a construction project, or "collapse" it's an unintentional tragedy. If I had to argue for "drop" I suspect it's advantage is that it describes how you want the building and the rubble to fall - down instead of out.
I'd be willing to consider the merits of different word choices, but what I think we should be hesitant about is drawing deep psychological conclusions from word choices that may be entirely coincidental or have a different motive than you think. E.g. "The author uses terms like 'drop' to disguise the horror of war and if such language weren't used we'd have less war." That feels like an overreach to me.
Not that the specific example is that relevant, as others have notice. I think it’s hard to deny that the military uses euphemisms: “soft targets”, “neutralize”, and “collateral damage” come to mind.
From there, it’s a small step to wonder what the intend may be. And even independent of intent (I could see an argument for using euphemisms with good intentions, or just to avoid very human emotions, much like medicine does), if that choice may still have the consequence of making difficult choices easier than they should be.
In any case, I was mostly just arguing that the idea that “language is meaningless, bombs kill people” is somewhere between ignorant and naive.
"Soft targets" include people, yes, but the term generally refers to any unhardended, unarmored, or unprotected thing.
"Neutralize" encompasses any kind of condition that removes a soldier from the battlefield, including death, injury, debilitating trauma, etc.
"Collateral damage" is similarly broad. It's any shit you didn't mean to fuck up.
No doubt these terms are used euphemistically at times. But I also can't, off the top of my head, think of any others that could directly replace them accurately and concisely, while also satisfying the demands of folks who lack the experience (or the desire perhaps) to understand their utility in context.
This is simply how military tactics and strategy are talked about in an academic sense. It might be weird to think that Military Science is an academic discipline when you're not used to talking about war all the time, but when you're at West Point you take these classes and this is the tone. It's because you're not going to stop every 5 minutes to reflect on those who died in combat -- that would be kind of crazy, and there are plenty of other contexts where the moral and ethical issues of war and combat are discussed in great depth.
To make an analogy, your comment would be like my reading a Computer Science paper about something technical and then commenting: "why is this person writing about technology in such technical terms? Is it because they don't want to confront the negative consequences of technology on our political and social fabric? Don't they care about the privacy issues?" It's kind of just a way to say that you wish they were talking about what YOU want to talk about.
People didn't die because of writing. They died because someone used the building to shoot at people and couldn't be flushed out with smaller weapons. So, the answer to your question is "probably zero"
