Heavy Weapons Trooper is what you would want to look into. Sandtroopers helmets would be weathered, as well as painted different and therefore not interchangeable. HWT would require a belt that you can remove the drop boxes for level 2 approval. Other than that, build a back pack, buy a Pauldron , get yourself a BFG and you can moonlight your TK as a HWT. Please someone tell me what I'm overlooking.
