I'd be a bit surprised if it didn't happen AT LEAST within the next two generations.
Anymore then that and I'd go "What the heck Military!?!"
Well, in defense of the military, they are extremely conservative. If it currently works, dont screw with it until it doesnt, just incase what you screw with breaks it. Thats the military mindset so many people seem have a problem with. But its not personal or sexist or immoral or racist, etc, its just that military screw ups tend to be rather, well, fatal and no one wants to be left holding the "good intentions" bag when their units get wiped out.
As far as timeline, considering how long it took african americans to be assimilated into regualr units, I would say 3 generations is about right.
As far as logistics, most modern militaries allready has women serving side by side with men. Combat troops make up a small part of the whole miltary apparatus. Combat support is huge. There have been logistics for women in place for decades now that are just standard part and parcel of life in the military. I dont think moving women into combat roles will effect logictics much at all.
Now we must devise a way of determining which men and women would serve with honor and respect for one another, and which would end up doing crap like those officers. And it must include magma.
Its called the UCMJ
