Not all military personnel are combat operatives.
The U.S. military also employs firefighters, plumbers, quarry specialists, construction engineers, secretaries, IT analysts, geospatial engineers, carpentry and masonry specialists, trainers, aircraft electricians, avionic engineers, helicopter repairers, multimedia illustrators, visual information equipment operators and paralegal specialists.
All transgendered people in all of those roles are no longer suitable to be employed in the U.S. military. Trump did not specify combat troops.
It's everywhere.
So, potentially right now, someone who has already transitioned (even before they joined the service), and is doing their job fine without any overhead to their employer, faces dismissal no matter how good at their job they are.
It's every kind of wrong.
