Than that really makes no sense to me because if you are deployed, assuming they mean a hazardous duty area, you get that pay, + many times a cut in taxes, so if anytime you could afford to pay it, it would be at that time due to the increase in pay.
It really appears that this is a program not worth the paper it is written on due to all of the squares that they must fill just to be eligible.
To me what is sad, is that many ROTC grads don't go AD right away, and many take student loans because they weren't scholarship. This means as they are awaiting to go and serve, they will have to worry about paying the loan, and if they can't afford them as a waiter at AppleBees, they risk their TS clearance due to credit issues.
Bullet back in 87, did not go to UNT for 9 months. He had no student loans, but if he did, he would have had to start re-paying 90 days prior to going AD. That was in a much stronger economy.
I may have missed something, but I did not see it stating you must be deployed. I took it as if you are AD, not in training, than you are good to go. UPT/UNT may fall into a different category, because you are not TDY, but actually PCS'd to these schools. TDY is anything under 6 months.
I took the deployment issue to say, they will give the deferment if you were forced to go AD, but not to mean you must be AD and deployed to be eligible for the deferment.
