False choice. The question is not, at least primarily, what can women do or can’t do. The question is how will the behavior of men change. Not just the obvious “Love Boat” issues but otherwise. Remember the Japs tortured captives on Iwo Jima and Guadalcanal in the hearing of their buddies.
True. I look at this in three parts not necessarily in the order of importance:
1.) Unit cohesion and dynamics
2.) Physical strength and capabilities of AVERAGE female vs AVERAGE male
3.) Logistical and operational consideration (assignments, maternity considerations, equipment differences gear/accomodations/etc)
