How do i upgrade my general under honourable conditions discharge to an honourable discharge? Will I have a better chance of reenlistment?

I had one from the Navy with and RE-4 . I enlisted in the Cal Guard with a waiver. IST ed to Washington state then went active duty Army and retired with 26 years service active duty. I will say i wasn't the best soldier when I was in the Navy I was a very hard worker just got in to too much trouble. I got a second chance and made the most of it and deployed 9 times for total of 9 years. 10 good = 1 ah shit as long as you know you have to make right with your past ways your good no excuses. God Bless good luck

I have people that I have helped.
You have to go to your prescher, sheriff, and any person that you know that are up there in the city, county or state government plus anyone you can get to say that you have changed into a fine person now.
With enough and the right ones they will change it so do not give up.

Wow. I have 2 honorable discharges from active duty, an one honorable from the reserves. I guess I could lend you one?

Why should you be able to upgrade your discharge? Those of us who followed the rules, did the right thing and received our honorable discharge, take issue with anyone being able to do this unless there is a high bar of extenuating circumstances which determined how you were separated! A lot of us who were Viet Nam or Viet Nam-era vets, put up with a lotta bullsh*t during our tenure in the military such as seeing the transition from a draft/volunteer in Army '72-'73, to an all-volunteer one and let me tell ya, some of us who were drafted then took extra time for schooling, saw a lotta street punks and thugs come in and thank God we didn't have any kind of military action to which must respond because we would have been screwed with all the "warm bodies" recruiters were lasso-ing! After writing this I noticed that you want to re-enlist, in that case I must temper my response...if you sincerely want to go back and serve "honorably" and straighten out some things, then I say more power to you and good luck! I would start by writing my Congressman.

It depends upon your reenlistment code. For example, an enlistment code of RE-4 means “unwaverably disqualified from further service” which is a permanent status. All others less than 4 have at least a possibility of reenlistment.

See your county or other Veterans Service Officer (VSO).

Be happy with the discharge you received. Also be glad it was with honorable conditions, as I know of a number of prior service that receuved a General Discharge with less than honorable conditions.
Like some of the other replies on here, it is going to depend on what your RE code is, along with what caused you to be booted to begin with from the Army. But like a retired Army JAG that is a neighbor told me, " ...chances are zero to none on getting your discharge upgraded to an Honorable..." So the best to you in your endeavor.

Didn't make the first time. What makes you think it will be different this time. No offense but those I've met in the past only did to obtain VA benefits
