08 Ms.... no matter who bring up this... i would also recommend them to go find the manga, which is the prequel to 08 Ms... which is done by the director himself, with the setting of Shiro in Side 2 colony that was poison gas by Zeon, and Shiro and team back then have to fight of the zaku team in the colony, and they all rely on guerilla style without MS (early Federation dont have MS). And the story protagonist is a female pilot of Zeon, Shiro is more of a side character representing opposition faction.
