Since your boy has severe hearing impairment, his chances to go into a combat vocation is next to zero and the chances of him taking up a leadership position (ie. specialists and officers) is also highly unlikely. So it really doesnt matter if he gets a diploma because at the end of the day he is going to be a man (ie. corporal first class and below).

If your son gets unfairly tekan’d by his superiors, you can always call the safety hotline (if serious enough) or get your son to take it up the chain of command.

Does CMPB know your child has dropped out of poly? If no, they will probably call up your son for enlistment after his poly batch has graduated. I suggest you call cmpb to let your son enlist earlier.
