Im Currently in the DEP and I am waiting to Ship to Ft, Jackson in July. My current MOS is 42A. But My overall career goal is to one day be a Food Service Sergeant. I was not able to get 92G at MEPS because It was discovered that I have a mild red/green color deficiency. I know that combat support MOS are able to get waivers for this kind of thing. I know that I cant re class until 24 months before my ETS date. My question is Can I just simply re class from 42A to 92G that easily?
