Let me tell you a story -
One of the most strategic persons I ever knew went to the USAFA, and because he had eyesight issues, was a missleman in the Dakotas. So after doing that for a few years and becoming a Capt, he applied for the law school program through the USAF and was selected as one of about 40-50 officers that year to attend law school. He went to the University of Florida (largely to defrost), and the military paid for his tuition, housing, etc., and paid him his salary as a Capt for three years. He owed them 2-for-1: in other words, he owed six additional years for the three years of law school. Well, he was a circuit prosecutor in Europe for about four-six years and thought that when he got out he would like to do something other than criminal law, so he applied for and was accepted for an LL.M. at Georgetown. Again, the military paid for tuition and everything else, except that by the time the year was out he had been promoted and was earning Major's money. Again, the 2-for-1 kicked in, but by the time he was done with his commitment (5+6+2=13), he was only 7 years from retirement, with three paid-for degrees and NEVER a missed paycheck. The guy is a large firm lawyer now making big $. THAT was the way to do it!
