So, how many transgender people currently serve in the military?
Well, a 2016 RAND Corporation study showed that of the approximately 1.3 million people who are considered active-duty members of the military in 2014, about 2,450 of them are transgender, making up about just 0.1-0.5 percent of the active-duty military. In addition, it’s estimated that about 1,510 transgender people serve in the Selected Reserve.
As far as future estimates, the study predicted that about 40-190 military personnel would seek gender transition per year, 30-140 would seek hormone therapy per year and 25-130 would seek actual surgical treatment a year.

For me thr take home point is that ~5% would seek surgery in a year and the same number start hormone therapy. How will this affect their ability to serve to full capacity. This is an issue that that these service people should resolve in the pivate sector, outside of the military.

Reading the article the process can usually take several years, cost ten thousand or more for surgery, $100 a month for hormone treatments, not to mention counseling. In the mean time they are to be treated as any other soldier requiring medical attention. When the hell do these clowns get down to doing actual soldering before their term of enlistment is up?
