A Certain Slant of Light

I don't know if there's a glut of war stories with this focus, but I suppose the neither brutal nor glorious angle would be focusing on the vast numbers of people involved in essentially drudgery of carrying out logistics... I don't remember it well enough to say whether this was a significant theme, but I recall parts of the WW2 narrative of Neal Stephenson's Cryptonomicon were somewhat like that? A major plot point that centred on someone's having gotten sloppy in choosing letters at random from a bingo machine for crypto pads, that kind of thing.

And yeah, I think that may have been part of the attraction :P
