Oh ok well see that pretty similar to what happened in my unit, Security Forces, and the commander ultimately has your fate in your hands. CC's will make recommendations to AFPC regarding what Airmen should be retained or not. For us, he is looking at EPR's, PT, CCAF and if you are operating at the level commensurate with your grade. for example, as a SSgt, are there A1C's and SrA's doing what you do.
Overall if your record and work performance is on point, you shouldn't have anything to worry about.
Have faith
