I am 41 years old with 4 years active duty Air Force. I understand that I am eligible to enlist in the Guard up to the age of 43. Is this correct? I have an honorable discharge but an AF Re code of 2Q. I hear that may disqualify me from any military service but recently I've been told I can get a waiver. Is this true? If so, do I have to do basic training, WTC, or either? Thank you for your time.
