Recently I changed my MOS to 91F 91J and 91J was the overstrengh. I start my classes at Fort Lee in July. I hope this new MOS is better than the last, because I could never do my job in 91J, but to help my fellow mechanics 91B. Let me know if I made a good decision, since the cutoff at this time are low. I am now E4 and not if with that of the low cutoff can be promoted to sergeant to graduate. Someone can talk about your experience in the 91F and the school in Fort Lee??
