“Join The Army,” They Said: While it’s never as yet been shown on screen, I am pretty certain both that the advertising is pretty realistic about the nature of war, but also that the recruitment slogan for the Imperial Military Service is along the lines of:
CIVILIZATION HAS ENEMIES.
KILL THE BASTARDS.
They’re very forthright people in the Empire, really (see also: Deadly Euphemism)…
(I mean, sure, it’s nice to have a bunch of big guys in power armor around post-natural-disasters, etc., and the IMS has a lot more tail than teeth, just like all modern militaries, so it’s not like most of them ever will kill anyone, even in wartime. But the reason it exists is nonetheless finding things that are looking to trouble the citizen-shareholders and then shooting the ever-loving crap out of them.)
