What system does the Chairman of the Joint Chiefs of Staff primarily use for strategic planning?

The Joint Strategic Planning System (JSPS) is the correct choice because it serves as the framework through which the Chairman of the Joint Chiefs of Staff guides the planning and preparation of military operations at a strategic level. JSPS integrates and coordinates the various plans and policies that shape U.S. military strategy, ensuring all components align with national objectives.

JSPS encompasses a comprehensive process that facilitates collaboration among military branches, supporting the creation of strategic guidance and planning that informs both short-term and long-term operations. This systematic approach is essential for developing coherent military strategies that can effectively respond to global challenges and threats.

The other options like the Combatant Command Planning System (CCPS) focus more on the operational aspects at the combatant command level, while the Defense Planning Guidance (DPG) provides overarching policy but does not serve as the primary strategic planning system. The Operating Plan (OPLAN) System relates to specific operational execution plans, which are derived from the broader strategic framework provided by the JSPS.
