What is the title of an individual who leads a unified command?

The title of an individual who leads a unified command is Combatant Commander. This position is vital within the framework of military operations, where a unified command generally consists of multiple military branches working together to achieve common objectives. Combatant Commanders oversee the execution of strategy and ensure coordination between diverse entities across various operational theaters.

In this context, a Combatant Commander is responsible for broader operational command and control, which is essential for joint missions requiring collaboration among different service branches. The role encompasses strategic planning and directing resources effectively, thereby maintaining unity of effort in dynamic and complex environments.

The other titles provided refer to specific roles within military logistics or command structures that do not align with the concept of a unified command. While they hold significance in their respective areas, they do not encompass the breadth of leadership and responsibility attributed to a Combatant Commander.
