That was mostly a decision by a not-so-good (and of course below-the-zone) DO and it was a while ago. There are good leaders in the AF and bad. I had my share of both. The bad ones don't get it and generally squash the good ones. I think the problem with the Air Force nowadays is the number one priority of most 'leaders' is to get promoted and that doesn't involve taking care of your people or getting the mission done smartly, it means making the numbers and your OPR look right. All else is way subordinate. Mistakes are frowned on (even the ones required in the learning process) and kissing ass is considered necessary.
