Without providing performance-enhancing (hormones) to our young women, I don't see how women can match the performance standards that would be required to fully integrate men and women into a cohesive boots-on-the-ground USMC infantry. Watching episodes of American Ninja Warrior and Spartan Race where the obstacle courses are 'gender neutral' (making zero accommodations for any gender) is an eye-opening example of what is possible, but few men or women could meet even those civilian standards (unfortunately the Coast Guard team came in last on one episode of Spartan Race). Will this be a failed military social experiment?
