I hear that often, but the trouble is that women and men together causes drama.
My son a marine, and I and my father have all served and all of us have seen first hand how there is drama, and flirting and a decline in unit cohesiveness. It is just not about if a woman can do the same physical , it is about a unit working together.
Yep there will be drama but only because it is a drastic change in the way things are done. But after it is implemented and becomes normal that will eventually change.
