Which annex would typically outline assessment criteria for subordinate units?

The correct choice highlights the function of Annex C, which is specifically designed to provide details on operational considerations, including assessment criteria for subordinate units. This annex is crucial for planning and execution as it clearly outlines roles, responsibilities, and expectations, which ensures that all units understand how they will be evaluated in terms of performance and success of operations.

Assessment criteria are vital for effective command and control, allowing for measurable outcomes regarding mission objectives. By establishing these criteria within the operations annex, commanders can ensure a unified understanding amongst subordinate units, facilitating coordinated efforts and enhancing operational effectiveness.

The other annexes, while important for their own functions—intelligence gathering, fire support, and logistics—do not focus primarily on operational assessments of subordinate units, thereby reinforcing that Annex C is the most appropriate choice for outlining such criteria.
