It was announced last year the Pentagon would provide sex-change operations to some transgender service members - if a military doctor found it was necessary.

The treatment could include behavioural health care, hormone therapy, and in some cases gender reassignment surgery.
Service members must be diagnosed as stable in their preferred gender for 18 months before they can receive treatment.
so, biggest baddest most $$ military on earth cries about a few trans people 😩 but funds the F-35? 😑 sounds like cowardice 😎💕🌈 #WeGotThis

Just because @realDonaldTrump was too chicken shit to go into the military doesn't mean he should ban anyone who chooses to serve country.
