Okay, here's the real answer. If you accept accelerated promotion to E-4 at graduation of A school, you owe then a fifth year of active duty. If you take the accelerated E-4 or not, you owe them two months of active duty beyond the required 4 for every month of training that you receive - whether you finish or not. You will not be admitted to the NF/ATF training until you sign this agreement. You do not have to "cancel" the extra time, your EAOS will automatically adjust to reflect the actual date that your active obligation ends. You can find this date on your LES every month. If your EAOS currently says that you owe them six full years of active duty, then you do.
