Let's leave up to the military to assign roles for military purposes which is the whole point I think. Leave politics out of it, leave agendas out of it and leave feelings out of it. The service is about killing better and faster than the other guy and should forever remain that way and whatever is needed to do that should be done.
I'm not a military man but I assume there are many roles available to women in the service other than combat which are rewarding, satisifying and very important. Besides in my old fogieness I think a woman should be saving lives rather than taking them but that's me.
I'm willing to abide with what's thought best for the military by our generals and our leaders when it's used for the purpose of defending our nation and not for social experiements.
I would say, though, that it is a crime to put anyone, male or female, into a job that they're not properly trained for and physically capable of performing. Performance standards should never be compromised for any reason-- and truly, performance is the only criteria that should matter.
