Medically indicated for the Military is very different from medically indicated in the civilian world.
By military standards, gender dysphoria is a psychological malady which is incompatible with military service. Heck, most psych maladies that require ANY medication are also indicators for medical discharge. In the civilian world, most are easily treated with meds. At the end of a long logistics line, those meds may be sporadically available, if at all. Imagine a long deployment, and a patrol deep in enemy territory. Would you REALLY want one of your squadmates to go off their meds, ESPECIALLY when many psych meds have rather nasty withdrawal symptoms. . .
