I already know one kid who is going to be using the transfer. His Dad has a choice, transfer it and let their son go to his dream school or saddle the child with loans.
When I was getting my Masters about 10 yrs ago, in all of the classes, I was the only spouse, the rest were split evenly 50% Enlisted and 50% officers. The officers need it for promotions, the enlisted did it because they knew that they had 1 more assignment in them, and the pay back committment for education would run concurrent with their PCS. I have never heard of a ph.D program that can be done at night, most of these guys will retire at 38, at the earliest, they can't afford to go for the ph.D, instead they go mgmt. because 50% retirement pay will not cover the costs for a family of 4 and one nearing college.
I also know of a guy who is transferring it to his wife, because he too has his masters, she does not have her undergrad, and they figure that if she gets her undergrad they will make more money.
