What type of command does the Joint Force Commander have over all service and joint component commanders?

• A. OPCON
• B. COCOM
• C. TACON
• D. ADCON

Answer: (B)

In joint operations the central idea is who has broad, unified authority to direct forces across the whole operation. The Joint Force Commander holds Combatant Command (COCOM) over all forces assigned to the joint force—this includes both service components and any joint components—giving the JFC the authority to plan, direct, and employ those forces to achieve the mission. This level of authority ensures a single, cohesive effort with clear, unified direction.

Other forms of command are more limited. Operational Control allows directing forces for specific tasks and missions within a broader framework, Tactical Control focuses on the details of conducting particular operations at the battlefield level, and Administrative Control covers support and administrative matters without directing the combat actions themselves. Because the question focuses on overarching command over all components, COCOM is the correct form of authority.
