My DS is applying to ROTC, and he has brought to my attention that there will be a very in-depth medical exam called DODmerb. He does not have any diagnosed medical issues that would result in him getting Disqualified, but at the examination, would they/could they find an issue with him and DQ him for good? What is the exam like? All he wants to do is serve and sees himself nowhere else! For those who have had experience in DODmerb, I would appreciate any advice and experience.
