If you've been hit you can send a signal with these brightly colored red "dead" rags. These rags are used for safety and are required at many arenas and fields to help prevent already shot players from getting shot again once they are out of the game. They also help signal to anyone who can see it that you are on your way back to respawn. Many times they are stored in pockets, pouches, and self-contained sleeves, they're often placed on the top of the head or around the end of the gun when a player is eliminated.
