Aren't they already? And what's the difference anyhow? The Officer has an orange shoulder-pad thingie as he's supposed to, that's the only difference I can think of, personally. If you know more than I do and can elaborate, that'd be great.
Edit: Only complaint I have is that they're not full of dirt and sand like in the movies. But then again, they have just disembarked their troop ships, at least on Mos Espa, so I guess that on that map, dirt wouldn't make much sense. Edit: Come to think of it, maybe the Rebels on Mos Entha could also slightly bloodied and tattered clothing, having just been in a corvette crash.
