From a blistering article by Army Lt. Colonel Paul Yingling:

"While the physical courage of America's generals is not in doubt, there is less certainty regarding their moral courage. In almost surreal language, professional military men blame their recent lack of candor on the intimidating management style of their civilian masters. Now that the public is immediately concerned with the crisis in Iraq, some of our generals are finding their voices. They may have waited too long. . .

Indeed, the tendency of the executive branch to seek out mild-mannered team players to serve as senior generals is part of the problem. The services themselves are equally to blame. The system that produces our generals does little to reward creativity and moral courage. Officers rise to flag rank by following remarkably similar career patterns. Senior generals, both active and retired, are the most important figures in determining an officer's potential for flag rank. The views of subordinates and peers play no role in an officer's advancement; to move up he must only please his superiors. In a system in which senior officers select for promotion those like themselves, there are powerful incentives for conformity. It is unreasonable to expect that an officer who spends 25 years conforming to institutional expectations will emerge as an innovator in his late forties."

Whether he's right or wrong, you have to admire his courage. Ask yourself: when is the last time you saw a mid-level manager in a business challenge his superiors like that?
