Leadership in the military works different than in other institutions. It is one of the only systems that I know of where authority is bound with responsibility. As a leader you are held to account for your actions and the actions of your subordinates because of your authority over them(IMO police should be held to at least this standard if not higher as they are granted permission to assault, detain or use lethal force against anyone as they see fit). It is common for NCOs to be reprimanded for the failings of the subordinates because it is often characterized that the leader failed them because they did not train or oversee them properly. There is some fault tolerance built in (with leaders spot checking leaders below them by checking their subordinates) but the system will break down if you have multiple levels of failed leaders within the chain of command.
The truth in the military though, is that this authority is mostly an illusion. There are many terrible leaders that do not understand this. They believe once you attain a position you are entitled to give whatever orders you like and that people cannot refuse them. This is true in civilian life as well as military. However, a good leader knows that their subordinates grant them authority over them. Understanding that, this is where much of the military leadership philosophy comes into play: lead by example, taking care of your team, morale, etc. These things are of much more critical importance in military roles because of the levels of risk, tension, and stress are often very high.
