Nonsense! All the movies show that little teeny tiny girls can whip six great big men all at the same time!
Also, it annoys the crap out of me that they use the word "Soldier" when talking about these scrawny little girls that are more trouble for the military than any possible benefit.
Keep em in logistics or medical, and leave fighting to men.
Problem not a combat engineer. She was working in the arms room. That's where you go when you are looking for the armorer. That was probably her job. She is certainly a Soldier despite your narrow minded opinion.
