Some years ago, unfortunately before I started storing links for things, I read a post by a military officer recounting how many female 'soldiers' 'suddenly' got pregnant just after they found out they were going to be deployed to the middle east, instead of at a military base in the US.
Or then there was RAF Pilot who suddenly decided 'We totally shouldn't bomb people' when she found herself faced with an actual combat mission.
A lot of women who join the military cause problems like this, and that's before you get into the ones who cause drama because of their romantic and sexual ambitions.
And until the politically correct drive for 'equal women everywhere' is destroyed or at least seriously weakened, western militaries won't be able to have honest internal reporting about it.
The west isn't the only one with female service members. All of our major adversaries, with probably the middle east being the only one that doesn't, have them as well.
So there is that, it isn't just a western problem. And they will do a lot of things to make sure they are used for more then military purpose.
Witnessed it first hand myself. 11 Females in the medical Platoon popped pregnant 2 weeks before deployment. 15% of the units strength just gone right there...before deployment even started. This was after the Battalion CO was relieved of duty for a standing order thst no female to get pregnant between that speech until after deployment ended.
I got lucky. A little more than a week out I got transferred to an all male Battalion. But I heard 7 more would get pregnant downrange. I think 5 of them were married and it wasn't their husband's who knocked up either. There was also a prostitution ring run by about 8 or so females (run by a Female LT as their madam) that got busted due to the fact they couldn't explain all the money they had and couldn't send it home. Careers ended for that too.
Some crazy shit.
See, this is something I knew about and have seen in person, but in diffrent ways.
The females that don't want to deploy and get pregnant like that, are often the ones that dont stay in long term.
They want the benefits of the army without doing soldier stuff.
Though it also heavily depends on job and on the person themselves.
Combat medic, I honestly expect that, but RNs, doctors, and ones like that? They may not do it.
I don't have numbers obviously and you do.
In my field, since er are not front line combatants, most do not try and get out of deployments, most go and try to get them.
