Rebel

The Rebel is basically an Acolyte, only fighting on your side. They are human rather than part mechanical, and therefore move a lot faster and die a lot easier, but that's really their only difference. They drop the same ammo when killed, and will fire on you if you attack Macil before a certain point in the game. It's possible to get caught in their crossfire, though usually they get caught in yours first, as their AI is incredibly stupid. In the maps utilizing a lot of rebel troopers fighting against the Order, they tend to die like flies.
