The authority to assign tasks and designate objectives is under which command function?

The authority to assign tasks and designate objectives falls under the operational control (OPCON) command function. OPCON refers to the authority to direct forces assigned to a commander for the accomplishment of a specific mission. This function includes the ability to assign all tasks necessary for mission accomplishment, making it crucial for effective leadership and operational success.

In military operations, OPCON provides commanders with the necessary authority to not only direct forces and resources but also to align their activities with strategic objectives. This is why the ability to assign tasks is fundamentally tied to OPCON, as it empowers commanders to execute their missions effectively and adapt to changing scenarios.

The other command functions, such as administrative control (ADCON) and functional control (FACON), do not encompass the same scope regarding task assignment and operational objectives. While ADCON deals primarily with the administrative responsibilities and support of forces, FACON is focused on specific functional areas and does not inherently include command over tactical assignments or operations. The general term "command" could refer to oversight but lacks the specificity required to describe the unique nature of operational control and its implications in task and objective assignment.
