I know how it can be frustrating to get stuck in a game like this and I am sorry that its not 100% clear. I am not sure what part of the rebel base you are stuck in exactly but this guy below has a video walk through of the game. If you are stuck maybe take a look and see if he can help you out.
He has another part after this as well. Sorry, i do need a bit more specific info on what part you are stuck at to give an exact solution to your issue.
