Catachan Land Sharks Company Commander.
Veteran Standard Bearer. It's ispired by Glory movie final scene. Torso and flag are from fantasy Chaos Marauders. Look at the Land Sharks 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 Land Sharks:
Land Sharks Command Platoon with Heavy Support Antitank Squads.
