I have a few I've decorated my range bags with. Nothing official typically stuff I find funny. However on my med kit I have the red cross thingy to mark it as a med kit as well as my blood type.
I'm a bum and bums don't have morale patches, it's counterintuitive to our way of life.
However, my brother is a fireman and I can see if he has an extra one I can send ya if you'd like.
