From the site description:
Kit Up is the stuff you weren't issued but that you couldn't have done without during your military life. Kit Up can be a device, software, book, DVD, or a resource like a website, chat room, or blog. We want to know about the items that made things bearable during a deployment or that allowed you to accomplish your mission. Maybe your gear even saved your life. Kit Up can be new or old, expensive or cheap. It just needs to have mattered to you. And if you used an item that you think works better than what's posted here, we want to hear about that too.
