Which level of war involves national or multi-national guidance?

The strategic level of war involves national or multi-national guidance as it encompasses the highest military objectives, integrating military power with national policy and goals. This level focuses on long-term planning and the direction of entire military campaigns that address broader political, economic, and social factors that impact national security and international relations. At this level, decisions are made by high-ranking officials and political leaders to allocate resources, form alliances, and establish overarching strategies that align with the nation’s interests or coalition objectives.

In contrast, the operational level connects strategy with tactical actions, dealing more with how to employ military forces in campaigns and major operations. The tactical level focuses on the execution of specific battles or engagements within the operational context. The supportive level is not a recognized level of war in military doctrine, making the strategic level the only correct choice that represents national or multi-national guidance.
