I will be the first to admit that I am not fond of the idea of women in combat. Once I went into aviation, I had female superiors and subordinates for the rest of my career. I will admit that there were some that may even have been better pilots than I am...and many that were not...but that goes the same for guys so is not a valid comparison.
We even had a married couple serving together once. From the instructor pilot side of the house, we often said that we wished we had one pilot with her brains and his stamina....then we would have Captain America for sure.
A few years ago I took a class through Norwich University...Race and Gender in Military history. I was not a happy camper. I took it as a default class because I missed an email instructing me to sign up for one of 3 classes or that would be the default....I'm glad I took it, it wasn't the touchy feely girls are just as good as boys type of class that I expected. It litteraly was about the contributions and challenges of minorities and women in combat.
think of women like Lyudmila Pavlichenko and a bunch of other German and Russian women during World War I & II. The Russian "Night Witches" would get a German an automatic iron cross if he shot one down.
With that in mind, there was an email a few years ago floating around describing why Arabs fight. It showed Israeli female soldiers vs arab female soldiers. I couldn't find the website, but here is one that shows the israeli side... http://english.cri.cn/11354/2014/02/12/2743s812445.htm the other side showed women in burraks, and sometimes women that you wished were in them. Pretty obvious reasons to fight.
That being said, I think the Kurds have a pretty good concept of the situation. The only thing left to do is to dip all of their bullets in pigs blood, that way every ISIS fighter that is killed is doomed to hell for "consuming" pork before he died.
