IDEA: When cutting a raincoat that the rags are the color of the cut clothes. These colored rags will be sewn to clothing and vests (using the leather and sewing kit) leaving the option of choosing simple shapes, such as a cross or a rectangle, to sew to the clothing. Leaving the option to sew it in different places: back, front, legs and arms.
Thus achieving clothing with signs of a color and shape that would allow the teams to identify themselves more easily and avoid friendly fire. Since the bracelet cannot be seen from too many angles and it is easy to find enemies with your own bracelet.
In an environment of war, both today and in ancient times, it has always been common to add elements to clothing to identify oneself more easily. I think it would be an easy change to implement and of great interest to players.
