I will allow that women don't have the physical strength of men. But we have the same level of intelligence and more dexterity, so who knows. My husband also, doesn't like to work with women because he feels they don't work as hard as his men do. I tend to see his point on that issue.
Which makes them shine in rear jobs, releasing men to ply the brutal and physically demanding job of combat. In my opinion, this is a large part of why we won a world war in two theaters at once.
