Step-by-step explanation:
An Officer Precedence Number or lineal number is a system used in the military to determine the relative rank of officers in a given branch or service. It is a numerical designation that indicates an officer's position in the chain of command. The higher the number, the higher the officer's rank and authority.
For example, in the United States Army, the Chief of Staff has the lineal number 1, while a newly commissioned second lieutenant would have a much higher lineal number. This system allows for a clear and standardized way to establish the hierarchy and authority within the military.
