The range of females that would meet the same Marine infantry officer physical standards as males most likely ranges from one in 100 to one in 1,000 or more. Physiologically, men are simply stronger than women and adapted, owing to our hunter pasts and to evolution, to life in the field in a brutally harsh ground combat environment. There’s much more that goes into successfully leading infantry troops in the field than just being able to exert eight pounds of trigger pull, after all.
It doesn’t make sense to me to surge women into ground combat infantry roles (armor and arty is still an issue, even) if their presence within such units is going to be mostly as a statistical oddity or anomaly. What’s the point or aim to that?
