This is, honestly, quite ridiculous in context. It might be true that, say, someone launching an ICBM might be shielded from the horror of the violence with clinical terms. When you are in urban ground combat it's not as if you say "hmm, it makes it feel better if I think of it as only shooting the building!" You are perfectly fine with killing because YOU'RE BEING SHOT AT and you're afraid you're going to die. The correct criticism, if you're looking for one, is that Soldiers and Marines learn to put on a facade of ultraviolent aggression so as to not confront the reality, and as a result they lose perspective and maybe go too far in some cases, and that's what you need to watch for (I was a platoon leader in Iraq)

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.
