What defines a Center of Gravity (COG) in a military context?

In a military context, the Center of Gravity (COG) is defined as a characteristic or capability that provides an advantage and sustains a military force’s operations. It is the source of power or strength that enables a force to achieve its objectives and purposes. Understanding the COG helps commanders identify the critical elements that must be protected or prioritized for successful operations. By focusing on the COG, military strategies can be developed to exploit strengths and target weaknesses in adversary operations.

The other choices do not capture the essence of COG as they refer to varied elements like a civilian population, a temporary asset, or a specific location, none of which encompass the broader concept of a vital capability or characteristic that enhances military effectiveness. Instead, the COG is inherently linked to the capabilities and attributes of a force that allow it to operate effectively and prevail in conflict.
