Command hierarchy

  (Redirected from Chain of command)

A command hierarchy is a group of people who carry out orders based on others authority within the group.[citation needed] It can be viewed as part of a power structure, in which it is usually seen as the most vulnerable and also the most powerful part.[citation needed]

In a military context, the chain of command is the line of authority and responsibility along which orders are passed within a military unit and between different units. Orders are transmitted down the chain of command, from a higher-ranked soldier, such as a commissioned officer, to lower-ranked personnel who either execute the order personally or transmit it down the chain as appropriate, until it is received by those expected to execute it.

In general, military personnel give orders only to those directly below them in the chain of command and receive orders only from those directly above them. A service member who has difficulty executing a duty or order and appeals for relief directly to an officer above his immediate commander in the chain of command is likely to be disciplined for not observing the chain of command. Similarly, an officer is usually expected to give orders only to his or her direct subordinate, even if it is just to pass an order down to another service member lower in the chain of command than said subordinate.

The concept of chain of command also implies that higher rank alone does not entitle a higher-ranking service member to give commands to anyone of lower rank. For example, an officer of unit "A" does not directly command lower-ranking members of unit "B", and is generally expected to approach an officer of unit "B" if he requires action by members of that unit. The chain of command means that individual members take orders from only one superior and only give orders to a defined group of people immediately below them.

If an officer of unit "A" does give orders directly to a lower-ranked member of unit "B", it would be considered highly unusual (a faux pas, or extraordinary circumstances, such as a lack of time or inability to confer with the officer in command of unit "B") as officer "A" would be seen as subverting the authority of the officer of unit "B". Depending on the situation or the standard procedure of the military organization, the lower-ranked member being ordered may choose to carry out the order anyway, or advise that it has to be cleared with his or her own chain of command first, which in this example would be with officer "B". Refusal to carry out an order is almost always considered insubordination, the only exception usually allowed is if the order itself is illegal (i.e., the person carrying out the order would be committing an illegal act). (See Superior Orders.)

In addition, within combat units, line officers are in the chain of command, but officers in specialist fields (such as medical, dental, legal, supply, and chaplain) are not, except within their own specialty. For example, a medical officer in an infantry battalion would be responsible for the combat medics in that unit but would not be eligible to command the battalion or any of its subordinate units.

The term is also used in a civilian management context describing comparable hierarchical structures of authority.


In sociology command hierarchy is seen as the most visible element of a "power network",[citation needed]. In this model, social capital is viewed as being mobilized in response to orders that move through the hierarchy leading to the phrase "command and control".[1]


Military organization
Typical units Typical numbers Typical commander
fireteam 3–4 corporal
8–12 sergeant
platoon 15–30 lieutenant
company 80–150 captain/major
300–800 lieutenant colonel
2,000–4,000 colonel/
brigadier general
10,000–15,000 major general
corps 20,000–40,000 lieutenant general
field army 80,000+ general
army group 2+ field armies field marshal/
five-star general
4+ army groups Six-star rank/Head of state

Regardless of the degree of control or results achieved, and regardless of how the hierarchy is justified and rationalized, certain aspects of a command hierarchy tend to be similar:

  • rank – especially military rank - "who outranks whom" in the power structure
  • strict accountability – those who issue orders are responsible for the consequences, not those who carry them out
  • strict feedback rules – complaints go up the hierarchy to those with power to deal with them, not down to those who do not have that power
  • detailed rules for decision making – what criteria apply and when
  • standardized language and terminology
  • some ethics and key beliefs in common, usually enforced as early as recruiting and screening of recruits


However, people of such compatible views often have similar systemic biases because they are from the same culture. Such problems as groupthink or willingness to accept one standard of evidence internal to the group, but require drastically higher evidence from outside, are common.

In part to address these problems, much modern management science has focused on reducing reliance on command hierarchy especially for information flow, since the cost of communications is now low, and the cost of management mistakes is higher—especially under globalization—than at any point in the past. It is also easier to replace managers, so they have a personal interest in more distributed responsibility and perhaps more consensus decision making.

Ubiquitous command and control posits for military organizations, a generalisation from hierarchies to networks which allows for the use of hierarchies when they are appropriate, and non-hierarchical networks when they are inappropriate. This includes the notion of mission agreement, to support "edge in" as well as "top-down" flow of intent.
