What term describes a source of moral or physical strength and power?

The term "Center of Gravity (CoG)" is often used in military strategy and theory to denote the source of strength or power for a system, military force, or organization. It represents the critical capability or resource that, if effectively targeted or disrupted, can significantly weaken or defeat that entity. Understanding the CoG helps strategists prioritize their efforts and resources in achieving their objectives, as it focuses on the most vital elements that sustain operations and morale.

In this context, the CoG serves as the foundation of an entity's strength, whether it is moral, such as leadership or public support, or physical, such as troops or equipment. By effectively identifying and leveraging this concept, military leaders can optimize their strategies and align their actions to deliver the most impactful results in conflict scenarios.

Other terms offered, such as "Strategic Advantage" and "Operational Strength," relate to aspects of military capability but do not encapsulate the singular foundational source of strength that CoG refers to. Leadership Effect pertains more to the influence of leaders rather than the core source of strength itself, making it a less precise choice in this context.
