The combatant commander's campaign plan is based on which of the following?

The combatant commander's campaign plan is fundamentally grounded in regional security assessments and policy guidance. This means that effective campaign plans are developed after analyzing the security environment and aligning military efforts with national and regional objectives. The assessment provides context around the potential threats, allies, and overall geopolitical landscape, which are crucial for the successful execution of military operations.

While public opinion and media coverage can influence decision-making and operational considerations, they do not form the foundational basis of a combatant commander's campaign plan. Rather, they may be considered in terms of operational security and public relations aspects but do not dictate the core strategy. Similarly, focusing solely on the needs of their specific service would not reflect the comprehensive nature of a campaign plan, which must integrate multiple factors beyond just one service's interests.

Thus, the essence of a campaign plan lies in its reliance on a comprehensive understanding of the regional environment and national policy guidance, ensuring that military objectives are met within the broader strategic framework set by higher authorities. This thorough approach typically contributes to the effectiveness and sustainability of military operations in a joint and multinational context.
