You're right of course. If they could FIND A WAY to put their females on the battlefield and try to fight with men, they'd do it in a New York minute.
It would get rid of those nasty females and save their precious men for "better things," whatever that is.
It’s actually the other way around in China at the moment. One Child had *huge* negative ramifications - they now have literally millions of men (IIRC, 38 million) who have no hope of ever getting a wife and slim hope of ever getting a girlfriend. That’s because due to traditional culture, couples chose to abort their girls and have a son instead. They had to end One Child once the imbalance became blatantly obvious.
The Taiwanese have women in front line combat roles, but that’s less for any diversity reasons and a lot more because they don’t really have much of a choice. https://www.taipeitimes.com/News/editorials/archives/2018/05/31/2003694021
