I think that it would be cool if you had a means to more easily identify yourself and people that you are hanging out with, by certain types of clothing you can wear. Don't get me wrong, you can wear similar or different clothing, but I mean something that would allow you to wear whatever you want and still tell who is in your group, so long as you have the items. For example, I can imagine you being able to tie a bandana onto your backpack, upper arm, or onto your gun. They would stick out a bit, but it allows someone to look at you and say something like "ok, you have the blue bandana on your arm" or even if you found enough, your whole group could have one color bandana. The reason why I am suggesting this is the fact that when all of my friends have military equipment, it is hard at a glance to tell the difference between them. I also think that it would be good for large groups or clans to have something they all could use to ID their group while allowing them to wear any clothing they want. I also think it would be fun to learn about what a group uses to identify themselves, and wear it in order to confuse or mislead them.
