Full command (FULLCOM) is the military authority and responsibility of a commander to issue orders to subordinates. It covers every aspect of military
operations and administration and exists only within national services. The term ‘command’, as used internationally, implies a lesser degree of authority than when it is used in a purely national sense. No NATO or coalition commander has FULLCOM over the forces assigned to their since, in assigning forces to NATO,
nations will delegate only operational command or operational control.

Operational command (OPCOM)is the authority granted to a commander to assign missions or tasks to subordinate commanders, to deploy units, to reassign
forces, and to retain or delegate operational and/or tactical control as the commander deems necessary. It does not of itself include responsibility for administration or logistics. Beside full command the gaining commander may task
organize only under OPCOM the assigned unit and thus assign separate missions to it and its component parts. A commander may employ assigned forces under
OPCOM for any purpose.

Operational control (OPCON) is the authority delegated to a commander to direct forces assigned so that the commander may accomplish specific missions or
tasks, which are usually limited by function, time, or location and to deploy units concerned, and to retain or assign tactical control of those units. It does not include
authority to assign separate employment of components of the units concerned. Neither does it, of itself, include administrative or logistic control. For forces
allocated under OPCON the gaining commander may not break up the organizational integrity of the force for separate employment. Under OPCON forces assigned may only be employed within certain constraints such as function, time or location imposed by the higher authority. For example, the forces may only be assigned for a single phase of a particular operation. This may be done for
national purposes in the case of a multinational context, where it is in a participating nation’s interest to constrain in some fashion the employment of the contributed force. Under OPCON the gaining commander may assign a mission to the assigned element that is distinct from, but related to, the gaining commander’s overall mission.

Tactical command (TACOM) is the authority delegated to a commander to assign tasks to forces under his command for the accomplishment of the mission
assigned by higher authority. Under TACOM the gaining commander may only allocate to the assigned force a specific task consistent for the accomplishment of
the mission and purpose assigned by the higher commander, that is, within the parameters of the current mission given by the higher authority. TACOM is used
where the superior commander recognizes the need for additional resources for a task but requires the resources intact for a later role. Under TACOM the assigned
force is allocated for specific tasks and is allocated normally for a limited period of time. This prevents the gaining commander from employing the assigned force in
a role or manner not intended by the higher commander. When the task is complete or the specific timeframe expires, the TACOM relationship with the
gaining force ends. TACOM is usually applied to specific situations and to elements that have unique capabilities.

Tactical control (TACON) is the detailed and, usually, local direction and control of movements or manoeuvres necessary to accomplish missions or tasks assigned.
TACON is generally used to indicate those units that will be located within another unit or formation’s assigned geographical boundaries, and by so assigning, the
gaining unit becomes responsible for coordination aspects within the shared area of operations. The gaining commander has authority to coordinate local defence,
force protection and terrain allocation.
