Having experienced both civilian and military employment I can testify that the term 'manager' means something quite different in each. A typical manager in many civilian companies has little to manage but him/herself and, maybe, an office with a contract cleaner. A manager in HM Forces is responsible not just for the work functions of at least several personnel but also their welfare, career progression and, in conflict, their lives.
If we get to the level of senior management comparison we see in the services lots of risk but only standard reward - in industry a fat cat salary accompanies risk and a bonus scheme usually kicks in if the company achieves normally mundane performance.
I guess we are really discussing the difference between service and self-service.
