I am currently a FC3 in the Navy with the NEC 1339. I really want to cross rate to SB. I have been in since August of '09 and graduated A school in May of '10. I have almost served the 24 months required and have been working really hard on my PST. I haven't taken one yet because i want very competitive numbers to help my odds. FC isn't at all what I thought it would be. I joined the military because i thought i would be boots on ground. My question is, is it possible for me to cross rate from one critical NEC to another, and how often has it been done? particularly from Aegis FC to anything in Spec War?
