Which of the following is NOT one of the 10 Principles of Joint Operations?

The correct answer is that reconnaissance is not one of the 10 Principles of Joint Operations. The Principles of Joint Operations, as outlined in joint doctrine, provide foundational guidelines for military operations and include concepts such as Offensive, Economy of Force, and Mass.

While reconnaissance is a critical component of military operations and is essential for understanding the operational environment, it is not classified as one of these overarching principles. The principles focus on broader strategies that guide the conduct of military operations, emphasizing general concepts of how forces should be organized and employed. For example, the principle of Offensive highlights the importance of taking the initiative in operations, while Economy of Force stresses the judicious use of available resources to ensure maximum operational effectiveness.

Recognizing the distinctions among these parts of military doctrine helps clarify the framework within which military operations are planned and executed, enabling a more strategic approach to joint operations.
