Article 134 Is a part of the UCMJ. That takes a court's martial.
Actually, you can be processed under the UCMJ at Captain's Mast, which is considered Non Judicial Punishment. You know, for stuff like going UA.
And yes, I've seen people processed for CO's mast under article 134, usually was added on when they had other charges, but wanted to hammer them hard.
As far as your bullshit about discharges? Did you know that while a member of the DEP the enlistee isn't actually considered active duty, but rather an inactive part of the Marine Corps reserve.
As far as who can discharge someone from the DEP? It's done at the level of the CO of the recruiting district. It is classified as an entry level separation (ELS), which doesn't require any courts martial.
As far as thinking that he can now go and join any other service? Not so fast, because part of the interview asks if you have ever tried to enlist in another service, as well as they ask you to bring your discharge paperwork in so they can check eligibility. If he was kicked out of DEP for behavior like this, it's very doubtful that another service would take him, and if they did, a waiver at the level of the CO of the district would be required.
But, keep on with your bullshit, it's apparent you don't know what you're talking about.
