Where can you find the definition of "unity of command"?

The definition of "unity of command" is primarily found in the SORN (Standard Organization and Regulations of the U.S. Navy). This document outlines the organizational structure and the chain of command within the Navy, as well as key principles governing naval operations. Unity of command emphasizes the importance of having a single responsible commander directing all forces engaged in a particular operation, which is essential for effective leadership and operational efficiency.

In contrast, while the SECNAV Manual, the Commander’s Handbook, and the Navy Core Values Document might provide valuable information regarding various policies, procedures, and values, they do not specifically define "unity of command" in the same authoritative context as the SORN. Therefore, for clarity on command structures and operational principles, the SORN is the key reference.
