Which of the following is NOT an essential element of a combat patrol?

Logistics is indeed not considered an essential element of a combat patrol. In the context of a combat patrol, the primary elements that ensure its effectiveness are support, assault, and security.

Support involves the necessary resources and personnel that enable the main operation to succeed, while the assault element involves the execution of offensive maneuvers against the enemy. Security is critical as it protects the patrol from enemy attacks and ensures situational awareness.

Logistics, while crucial in a broader operational context for maintaining supply lines and ensuring that troops are adequately equipped and sustained, is not directly an element of the execution of a combat patrol. Logistics tends to be more related to the overall operational planning and support rather than the immediate actions taken during a patrol, making it the correct choice in this instance.
