I joined the UNAF when the Woolies attacked the colony at 47 Ursa Majoris, like so many people did. By the time I was through basic training and zero-gee combat training and astrogation training it was a year later and the Woolies had taken everything up to and including Epsilon Eridani.
My unit is all greenhorns like me and old men with the shakes, and we're all that stands between the enemy and Sol. I can still hear my father saying, but you're just a girl.
Not a problem.
