Because a guy with a pregnant wife/girlfriend doesn't have to be pulled out of the line. A woman with morning sickness or who is 8 months pregnant isn't going to be the best soldier in the foxhole.
Missed the story you referred to.

The only times I know of where men and women could effectively work together in combat were times where discipline was strict. During WWII the Serb partisans had mixed sex units without problems. Sexual contact resulted in immediate execution of both parties.
There was a US Army case in Iraq early on. A young woman was assigned to a night defensive position, an easy one, too, a nice big comfortable bunker, lots of guys to take care of her. She went hysterical, blubbering, screaming, a tantrum, a panic fit. Disgraceful. General Patton was right, the only way to deal with such things is immediate execution.
Takes two to tango, why is it always the woman fault?
Sounds like a discipline problem to me
Exactly! Having just men aboard ships gets rid of the problem, discipline or otherwise.
