It seems mostly mainly dull lists of military ranks, just the one character (seriously, everyone else in the book is literally passing through) who's dull, unlikable, and frankly bit of a dimwit, and padded with endless, endless pages of waffle on military 'morality'. And no it hasn't aged well, which I could forgive it, but for being supermassively yawnworthy, I can't.
It's awful.
