Which title is given to the individual who leads a Joint Task Force?

The title given to the individual who leads a Joint Task Force is "Joint Force Commander." This designation reflects the overarching authority and responsibility the leader has for planning, executing, and managing operations that involve multiple branches of the military and often include collaboration with civilian agencies and, occasionally, international partners. The role of the Joint Force Commander is critical in ensuring unified command and coordination among the various services and components involved in a joint operation, which can be complex and multifaceted.

While other titles such as "Joint Task Commander" or "Task Force Leader" might suggest leadership roles, they do not carry the broad scope implied by the Joint Force Commander designation. The term "Operational Commander" can also refer to leaders in various operational contexts but lacks the specific connotation of leading a Joint Task Force that the title "Joint Force Commander" encompasses.
