Catachan EartSharks Company Commander.
Veteran Standard Bearer. It's ispired by Glory movie final scene. Torso and flag are from fantasy Chaos Marauders. Look at the EarthSharks patch: I've drawn it (with windows paint...) and then I've replicated it in the flag with a very small brush.
Squali Terrae, latin for Earthsharks:
Earthsharks Command Platoon with Heavy Support Antitank Squads.
