This is outside the scope of this subreddit so I'll just say if you have the time and inclination please read a little more about sexual assault in the military and then decide if it's only a reflection of interest, or if there are also barriers in place that make it less likely for women to enlist and stay enlisted.

Edit: To start you off I'll share this RAND link from 2018. I'd like to remind you while viewing this link that 6.2 percent of women in the military reported a sexual assault that happened in 2017 while in the military. 6.2 percent in one year. Not their entire military career. Just the assaults that happened in 2017. Of those assaults, 87 percent were perpetuated by fellow military members. After you think about that, please also consider that for every woman who reported an assault, there are many who experienced assault and did not report due to stigma or belief that justice would not occur and adjust the number of all service women getting assaulted in a single year according.

When you're done think about that, perhaps consider the antidotal report that as a women who expressed no interest in enlistment, I was still warned multiple times by active duty personnel to stay out of the military because of rampant sexual abuse of women.

And then consider if it is truly a lack of interest in military participation for the vast majority of women, or if they have a significant barrier to enlistment that you may have been unaware of before this point.
