Congratulations for your and your son.
As a corpsman(medic) ..when he gets out he can step right into any VA hospital that has an opening
..some will make a spot for him even.
They are golden.
If he decides to pursue that career he has a leg up on most ..Licensed Practical Nurse, RN, Certified Nurse Aneasthologist
..even Doctor are very much achievable goals.
Met a few here an there while I was workin as an LPN
..they all said it was a short step to become an LPN when they got out of the service,
.. every one I met was workin on their RN college courses and planning to go up the chain from there.
