Gaius Julius Caesar
Black Belt
The only similarity is that there is a hierarchy. Military rank is a vehicle for military command. Nobody in a dojo is going to "command" me to do squat.
True it is the same but it is heavily influenced by Military rank structure and no one here "Commands" anything but they do lead.
I have found in both work and MA that things work better when people know where they stand and where they can go. Less arguements, confussion and emotions and more getting the mission done.
