In uniformed organizations with traditional functions, anything that attempts to make senior and junior people equal in some fashion, is indeed dangerous. In battle on a battlefield, orders are given and followed. Period. Or else people could die. If the person giving the orders is incompetent, people could die as a direct result, and for that I know of no remedy (not before it's too late, anyway).
In the Puzzle Palace (aka Pentagon) and its various extensions, including the systems commands and engineering and procurement activities, the effect of leadership is translated into team effectiveness, often expressed in cost, technical performance, and schedule compliance. Leadership in that kind of atmosphere contains a mix of uniformed and (often) formerly uniformed civilians, although there is a growing portion of the civilian ranks that joined the Government straight from college. The quality of leader is in part supported by an aggressive training regimen and several avenues for grievances and redress. The leadership style, in this atmosphere as in others, varies with the organization and its function and the individual situation.
I think the best leaders are those who take responsibility for the effectiveness of their organizations and do whatever it takes to ensure success of the organization, whether the task at hand is winning a battle, saving lives, maintaining complex equipment, or other more specialized functions. These leaders are motivated, energetic, positive and intelligent. There are other attributes harder to name, but folks who have worked for this type of leader seldom fail to realize that that leader was SPECIAL.
