Or she could become a hero of the imperium as a commisar, sororitas, or maybe even an inquisitor. In the 4ok fluff, when a woman is allowed into the ranks (sororitas included), she is almost always a badass.
Not sure if your making fun of me or just being witty -_-. But anyway. She is a Commisar's daughter. I think she will become someone important in the future
Except for the countless nameless imperial guard-women who die by the thousands alongside the men, or the secondary female characters that wind up on the wrong end of a slaughter.
Helsreach comes to mind, most of the Soritas died there; a guard chick and officer survived but one wasn't that significant and the other was more of a logistics and communication officer. In Heresy novels such as First Heretic and Betrayer they had significant female characters that died, as well as not-so-significant. Also Imperial Guard dies a lot in fluff, and they have women in uniform.
