My best friend just enlisted and is getting ready to ship off to boot camp in January. I want to get him something for Christmas that he might find useful while at boot camp. Seeing as how I don't know much about the military, protocols, the training, etc., I thought I would you all.
Anyone have any good ideas on some sort of tool or piece of equipment that could be useful? He's 27 and a bit of a "survivalist", so anything in that vein is probably a safe bet, I just don't know what he's allowed to bring along.
Edit: He is enlisting in the Army.
