Who has the authority to organize forces, establish subordinate commands, and assign responsibilities?

The Joint Force Commander (JFC) holds the authority to organize forces, establish subordinate commands, and assign responsibilities within the scope of a joint military operation. This command structure is critical for ensuring that military operations are conducted efficiently and effectively, with clear lines of authority and responsibility.

The JFC is responsible for coordinating multiple branches of the military and integrating their efforts to achieve strategic objectives. By organizing forces and creating subordinate commands, the JFC can delegate responsibilities to various leaders within the operation, ensuring that each component of the joint force operates cohesively and supports the overall mission.

Other roles, such as the Combatant Commander, while integral to military operations and strategy, typically focus on broader geographic or functional areas without the specific operational command authority that a JFC has in the execution of a joint task. The Joint Task Force Planner provides support in creating operational plans but does not have command authority. The National Security Advisor advises on security policy but does not directly organize or command military forces. Thus, the authority and responsibility for organizing forces and assigning roles specifically rests with the Joint Force Commander.
