The sniper/scout looks great. When the first space marine scouts came out they had the look of grizzled special forces veterans who'd been in the jungle just a little too long about them; like Edson's Raiders (to which unit I have a family connection) or Merrill's Marauders. Carrying enemy weapons, because maybe the like them better, and always half naked and completely dangerous. Your fellow has that look about him. I always liked that vision better than the "recruits" they turned them into later. Your fellow looks competent, determined, and very very dangerous. I like him.
