Can a character of discharge from the USMC be changed from General to Honorable?

I would say no you can't

Generally speaking, yes it is possible but not very likely. The percentages of character of discharge changes are very low...like less than 2% low.

Good Morning Sir. I'm not here to bash you. I want to attempt to give you sound advice the best I know. Based on your discharge, I would seek advice from your local VSO and ask them for assistance on upgrading your discharge from a General (under Honorable conditions) to an Honorable. Remember, just be forthcoming about everything what happened even if makes somewhat makes you feel uncomfortable so that they can effectively help you. I'm sorry that this has happened to you. I pray that everything will work in your favor. God Bless You.

how about the US Army

Anything is possible. Your story seems a little weird to me. Taking a good face Value. You did something stupid And command overreacted and punished you unfairly. If you really have a case There are lots of legal People That you can go can't talk to And apply for an upgrade. What do you get it or not depends on the very detailed facts of what really happened. Beyonce with yourself first And decide whether they're going to believe you, Or if you even have a case. Asking a question on this WebpageIs not going to help you at all.

I feel that you are only giving us part of your story. If what you have writen is true, one offense ,then I would ask for an upgrade. If it was one of several then I would accept it as it is and be thankful it was not worse.

There are some forms you can fill out and try to get it changed, But you can use your benefits as long as you were discharged under honorable conditions.

Get a VSO to fill out the paperwork and have a veterans organization like American legion go before the board to represent ya they can't give you a gen or undesirable for just one ua you have to have 6 or more njps or a court martial for that, sounds like someone screwed you royal in order for that to happen you should be able to get that cleared up with no problem

Well never say never, however, one NJP usually doesn't result in a General discharge. To receive an upgrade, from what I have heard, there either has to be a miscarriage of justice (of which you publicly admitted you committed the crime, so that is out) or serious and egregious errors in the discharge process (which doesn't seem to be the case). Even though it has been a long time, the upgrade process doesn't really account for that. You can look at this like the civilian equivalent. The NJP is a criminal conviction, possibly a misdemeanor in this case or it would have been a full fledged court martial, you will always have that conviction. The discharge is a tangible record of the conviction. Just like a pardon or clemency in the civilian world, it is extremely rare to upgrade a discharge, so I wish you luck.

As one who dealt with a few unreasonable ans way out there situations, I can't claim to know everything, but it sounds suspect. Maybe fill in the blanks if you're hoping to vindicate yourself?
