Forum:MGS4 battles. Can they be won?

I was wondering in MGS4 if you can actually win the battles located around the world during Act's 1 and 2. I know the rebels fight a long battle in the Middle Eastern section, right before you enter the Palace, and when you reach the Vista Mansion they seem to be fighting for hours. Is there a way to help them win or is it just an endless battle in those two places?
