Some of you who have served may be familiar with the challenge coin. For those who arent, they are basically collectable coins that are specific to various commands, ships, operations, etc. One my colleagues at my command used to be enlisted on the USS Tennessee, a ballistic missile submarine. He knew how big a Tennessee fan I am (I have a Peyton signed football, numerous framed pics of Neyland Stadium and various UT paraphenalia in my office) and showed me his coins from his time onboard. I love that they incorporated UT Big Orange, Volunteers and Davy Crocketts long rifle into their official coin. Pretty tame story, but I thought some of you may find it cool.
