Cool thread!
I'm still a random student (my dad an engineer), so I'd probably somehow bump into the latest proto-type Mobile Suit, and I'd magically be able to pilot it. Then I'd bump into some guy with a mask, develop a love-hate relationship with him. Then somehow save the day.
Just kidding.
Well I'm a student, and I don't think I can help out in a war apart from being a useless grunt in a Zaku or a GM. To be honest I'm working my way in life to be an artist, and I really don't want to die in a war, so I'd try my best to run away from it. I'd probably be one of those no-name civilians that die in a colony drop
