The "big picture" problem is that military members are not supposed to be "individuals" with "individual identities".  That used to be part of the lesson in basic training (boot camp).  The white farm boy from Iowa is no different than the black boy from The Bronx or the brown boy from Puerto Rico.  All of these people are/were taught to be a "unit" as in work together and for each other.

If you get a guy with a clear mental disorder (thinks that he is a female) that would be immediate grounds for separation from service.

At least that is the way that it used to be.  In today's military they are allowing soldiers/sailors to be "individuals" rather than part of a "unit".  That kind of system is doomed for failure.
