Transgenders suffer from "gender dysphoria,” previously known as "gender identity disorder," which is classified as a mental disorder by the American Psychiatric Association.  Severe distress, anxiety and depression are the most common symptoms.   Many straight service members are diagnosed and treated for such symptoms while on active duty, which often times become disqualifying medical conditions for continued service in the military.  When that occurs, service members are either discharged or retired for medical reasons and receive life-time compensation for their disabilities.  It makes no sense to allow transgenders with gender dysphoria join the military services when service members who exhibit the same mental conditions are being discharged as unfit.  Gender dysphoria should be a bar to enlistment in the armed forces just like other mental disorders.
