What are some of the best deployment living quarters hacks you've done or have seen?

I've been on my share of deployments, and despite the easy punchline of that I'm retired Air Force...how would I know Spartan conditions, what are some of the best "life hacks" you've done for your work centers and living quarters?

My first experience with making things a little better was when I deployed in support of Desert Shield. If there was a box or stray card board laying around, bam, it magically became a shelf or a night stand next to the cot. It seems pretty simple, but I think we all know "it's the little things that keep you fit to fight".
