Apart from the fact that you quoted her wrong, (she didn't say what you said), proving that she's wrong would presuppose that she's right. Which is not the case.
And to answer your other question: They distract males, cant handle the loads of equipment over a long period of time because they're not as strong as men, and it brings down morale if men see women die in front of them. Women should give live, not take them. It's better if only one gender is confronted with the shit that's going on at war.
