Transgender military ban

SCOTUS sided with POTUS (because of course they did) on transgenders in the military. They say there are roughly 4,000 (but the real number is probably much higher) that are serving and protecting this country that doesn't seem to want them. There is now years of data that refutes Trump and Hegseth's claims that they disrupt military readiness, which obviously doesn't mean anything to this administration. My question is, does anyone know what happens AFTER they are "dismissed" from duty? These people are veterans, they have been to war, they will have the same issues other vets have, PTSD, injuries and so on. Will they have access to veterans Healthcare? What will be on their dismissal record? I don't understand how they can do this to people who have willingly signed up for duty to fight for, die for, and protect this country.
