Which of the following is NOT one of the nine common elements found in combat?

High morale among troops is indeed not one of the nine common elements found in combat. The nine elements typically emphasize the chaotic and stressful nature of combat situations, focusing on aspects such as confusion, uncertainty, and the psychological and physical impacts of warfare, including casualties and feelings of isolation.

While high morale is certainly desirable and can enhance unit cohesion and effectiveness, it does not align with the common elements of combat scenarios, which are more about the challenges and adversities faced in the heat of battle. High morale can exist, but it is not an inherent element of the combat experience itself, which tends to highlight negative conditions and the struggles that soldiers endure.
