The commitment is what it is (to use an extremely overused sports term), and should be decided on by the government. Any time put in by guys after that is bonus time. Always irritated me when guys served their commitment but still got grief for leaving "early" once their commitment was up. Somewhere along the line, the AF determined that 8 years was a fair exchange for going to UPT, so that should be good enough for the rest of the guys. At any rate, I would've signed 20 year commitment at age 22 if that meant I could've gone to UPT. Of course, I'm glad that wasn't it, but I still would've signed it.
