Warriors of the legions use heraldry markings to signify the unit specalties. There are sizes of the Astro Sharks chapter markings for Kneepads, Shoulder pads / Pauldrons, Banners and Vehicles. The decal is printed in white on clear decal film so the image will stand out over a dark background. These waterslide decals are compatable with Warhammer 40k and Infinity miniature games.
