Here is my idea, if you guys don't like it, that's fine, we can change it, this was just what I was thinking, 

Zeon has created a new base of operations in space, one made to mass produce Gelgoog and other high priority mobile suits, Our mission is to take out this high level target and then move to take out other smaller bases and forces along the way, the reason we are being targeted is not only because we are on a crash course with an important target , but also because maybe we get caught once by them leaving Jaburo and now , there Ace pilot has a vendetta against us
