Pournelle, who if I recall correctly is a veteran of the Korean conflict, does mention logistical details more often than I expect in MilSF. Not the fun kind of logistics, involving the production of a million zillion Squamoid Hypermissiles, but the mundane sort, like who gets to dig the latrines. Latrines are not romantic, but nobody wants a battle called off because the men all have dysentery and are too busy shitting blood to fight.
