The military in general seem to be more rationally grounded than civilians, as far as work is concerned. Promiscuity with death must encourage a different "work culture".
It’s a giant government bureaucracy, with plenty of stupid internal politics, and gross incompetency. No better or worse than any other large organization.
My direct experience is very limited, but I've heard a few decent things from people better involved than I am. I suppose "the military" is a wide thing, there must be consequential differences between, say, American bureaucrats and French field soldiers in Africa for example. The former shouldn't be as close to death, or to soldiers who are, on a daily basis.
