You should post in the Jedi Knights Series Forum?
But yeah, whenevey Roschie falls the two red guys would try revive him, you can give them a nice whipping, use Lunge(light) or the big smash(heavy) on them. If you are quick you can kill one of them, kill both red guys. Shouldn't be too hard really.
You can try to catch them red guys also but they move kinda fast when not healing, and they can dodge guns.
Oh, and have fun would your saber, mind as well.
