I want to get my re 4 changed so that i may enlist in the national guard

You MIGHT be able to enlist--but it’s a verrrrrry slim shot. I am guessing you were Navy--had a weight or other physical issue--a waiver is technically possible if the issue is fully resolved; but has to be done through the recruiters. Most RE4 are NOT allowed to reenlist and those that are must do so only through the service branch they were already in (i.e. a Sailor only has a shot at reenlisting in the Navy--not the army). HOWEVER, it is UNLIKELY an RE4 would be successful in getting a waiver approved--here's why: two active wars winding down, military budget and personnel cuts--MANY are leaving active service and returning to NG or reserves--the NG doesn't have particular reason to take RE-4 personnel when they have lots of RE-1 and 3's who want in--it's a numbers game and you unfortunately, have the wrong numbers. Navy Reserves likely in the same boat (pun intended). See a Navy Reserves recruiter to ID you have any chance at all. Best of luck.

I agree with everything Mr. Rafter said, but would add the following: We have had success in getting some RE 4 codes upgraded, but you have to prove that they gave you the wrong code. For example, if they gave you an RE 4 for a "personality disorder" (a fairly common event) it is possible to get it changed if you can prove you did not have a personality disorder. But as Mr. Rafter said, even that is not a guarantee you will be able to reenlist, due to the draw down of the forces.

If you have a separation code of JFV, that means you likely were discharged for this reason: "Physical condition, not a disability, interferring with performance of duty, USN - Enlisted" If that's the case you won't get a RE change from the BCNR unless, as Mr. Cassara says, you can show you didn't have that condition at the time of discharge, and don't have it. Refer to Army Regulation 40-501 for the physical standards required to enlist or remain on active duty.
