2 days to about a week is all you should expect in the fridge. In addition, it depends on how old it was when you smoked it. If it was about expired, you don't get to add time to it just because you cooked it.
AIT = Advanced Individual Training This is the training you go to to learn your specialty (whatever your MOS is) after BCT (Basic Combat Training).
