I was recently selected for OCS and the SNFO program. I am a prior service Marine and the Doc there noticed I had Grade I Spondylolisthesis. This was waived at MEPS during my Navy Officer Phsyical because it was very minor and I was in good condition. They didn't really care and thought I was good to go for military service. I read up on the NAMI waiver guide and saw it can be waived for NFO's. I was just wondering if anyone else has had this problem and had been able to get it waived during a flight physical.
