The Purpose of the Chain of Command
The chain of command is the system used to ensure that each individual receives instructions for a particular task from only one supervisor. It is an authority and accountability chain from the highest office or position within the chain to the lowest element. The chain of command assists commanders at all levels to achieve their primary function of accomplishing the organization or unit’s assigned mission while caring for personnel and property in their charge.
A chain of command provides proper avenues of communication. It allows for members to give and receive information. When used properly, it is both simple and effective.
The chain of command varies based on the command involved. All orders and instructions should be issued through the chain of command. A person or unit can only have one immediate commander who issues orders and provides instructions. Using the chain of command, an individual commander may limit the number of personnel who are directly supervised.
