Our military is not now, nor has it ever been, an equal opportunity employer.  The military rejects plenty of people for being physically unfit for duty, as well as for a multitude of other reasons, like being over weight, mentally unstable, having poor eyesight or for being flat footed, they're not fixed first, they're rejected outright!   
The military is to be mission focused and battle ready, but as usual, the LGBTQ community expects rules and expectations to be different for them.
