I was in the Airforce and was discharged with reentry code 2B,Separation code JHJ. Reason ,unsatisfactory performance. I didn't pass (my pumper) Fireman test. AF, just kicked me out, in 2004 I know that the Army has a waiver that you can aquire to go back in, Is it a possibility for me to go back in? I will do anything possible to go back in . Please help me out?

Look at Army Regulation 601-210 Table 3-3.

Yes there is a waiver that you can receive. The only thing you need to do is take all your source doc's and your DD 214 to your local Army recruiting office and let them get you in the Army. You would probably have to meet some other requirements but as long as you are not fat or on drugs you should be ok.

If you refer to the regulation I posted above, you will see that some RE-Codes are waiverable and some are not. That particular Code says "Not eligible to enlist".
