After serving in the Guard for 20+ years I was not retained (unknown reasons) under NGR 600-102. Since then I have been serving in the USAR (8 years) I am currently on a 1 year tour in Iraq and would like to know of I can re-join the National Guard. Are waivers required for this to happen, If so who are the requests forwarded to? And by what authoriity can the Guard take me back? I have no ghosts in my closet, all 1 block OERS and meet Height and weight. If you know of a I can re-join the guard, I would appreciate your advise.
