What aspects are considered part of the operational level of war?

The operational level of war encompasses the broader aspects of warfare that connect strategy and tactics, focusing specifically on how to achieve the campaign's goals. The correct choice identifies key elements critical to understanding the operational environment and how to influence it.

Identifying adversary Centers of Gravity is crucial, as these reflect the sources of an enemy's strength that could be targeted to disrupt their capabilities. Monitoring events in the Joint Force Commander's (JFC) area of interest ensures situational awareness and informs decision-making processes. Focusing on enemy military capabilities is essential to understand potential threats and formulate effective operational plans.

These elements align closely with the operational level’s objective of translating the strategic vision into actions that will achieve tactical success, making them fundamental components of military planning and execution. Other choices, while relevant, emphasize aspects either too tactical or too strategic without highlighting the direct operational considerations that influence engagement decisions and resource allocations in the field.
