I am in deployed right now too, and what I set up was a 25mm ammo can, and I got a few cedar cigar boxes off line and broke them down and put the pieces on the bottom, and took the tops off the others and am using them as trays, and threw a couple of Boveda 72% humidpacks in along with a digital hygrometer. its holding at a 70 - 75% humidity. Works for me! Just make sure to let the can air out a while, mine smelled like gun powder for a few days at first.
