Thanks Tim for you prompt reply!
I played this using your #2(five rallies total) approach since the rule did not say that you could only use one per force. It only states, as you mentioned, that you gain one rally for each force. It does seem a little ambiguous, but that is how I played it.
Okay, that is what I thought too, but sometimes you get stuck at certain sentences/phrases, and you brain won't let go until you have got it verified by someone else!
