There seems to be a disconnect here between what the say the facts are and what you are saying is happening to your son. Marines
aren't given an unfavorable discharge for getting beat up, so there must be more to this than you have shared with me, or that has been shared with you. In any event, if your son was awarded nonjudicial punishment for misconduct of some sort, then if it was serious misconduct or he has a history of getting into minor trouble, then his Command could indeed be processing him for administrative separation
with an Other than Honorable characterization. If he waives his right to a Board, or is otherwise separated with an OTH, then he will generally not be allowed to reenlist in the future, although there are exceptions and waivers, depending on the circumstances.
If he does not have a prior Honorable discharge
from a prior enlistment, he will not be eligible for GI Bill
benefits. However, if he did have a prior enlistment and received an Honorable discharge for that, then he can still claim his GI Bill benefits. Other than that, he can still apply for VA benefits
, however, since he would have a OTH, those benefits would not be guaranteed and the VA would make their own separate decision based on the facts of his case and what he is applying for.
In terms of effecting his civilXXXXX XXXXXfe, there are some employers, mostly Government jobs, that do not hire someone who received an adverse discharge. However, for the most part, it won't effective most private employer hiring decisions.
Please let me know if you have follow up questions, I would be more than glad to answer them. I generally don't work on Sundays, so if there is a delay in my response, please forgive me and I will respond as soon as I am available.
