Command hierarchy
A command hierarchy is a group of people committed to carrying out orders "from the top", that is, of authority.
In sociology it is seen as the most visible element of a power network, which itself usually organizes many social networks. The entire network has social capital which is mobilized in response to the orders that move through the hierarchy - and closely controlled. This leads to the phrase command and control.
In the military the term CCC is sometimes used to include "communications" as the "third C". Since military situations involve disrupted, hurried, confused or deliberately intercepted and altered communications - see signals warfare and information warfare, and also a degree of manipulation of emotion - see psychological warfare - it is important that communications be closely monitored to ensure that command actually results in control.
