They're really just specifically geared up, the way a special operative would be. Which is what they are. They actually look like they can shoot and hit something haha. But to each their own! I can respect where you'd prefer a variant of the Shadowtrooper. I love the tactical load out that they have, it makes them distinct.
I was talking to my cousin this weekend and she said it would be really cool if they would introduce them in the movie with just the glowing green lights in their helmets appearing in a dark room, closing in on a target. Show them as elite, efficient, and stealthy soldiers. Make them scary, the boogeymen in the dark. I think it's safe to assume the green lenses and lights are supposed to represent night vision capabilities anyway.
