The Corrie Guard was a mess all the time, every day, even when showing up at official events. I mean, they put in so much work they earned it at this point.
No one was quite sure when it started, the premature grey hair, the insane amount of alcohol intake- the… ones who couldn't keep up? Ate a blaster bolt. None in the GAR noticed the slip until it was too late. The Corrie Guard got lazy and stopped trying to save face.
It started with small things, such as drinking while doing paperwork, popping a pill during a meeting, falling asleep standing up in the corner during meetings with commanders. Then it got bigger. Showing up drunk to meetings, drinking in front of commanders and generals, cursing out high-ranking officers, sleeping in meetings (flopped across the table), and generally not caring about regulations or anything else. And this was how it happened.
