The operations section chief is responsible for all of the following except:

The operations section chief plays a crucial role in the incident management system, primarily focusing on managing and overseeing the execution of operations on the ground. This role involves facilitating the implementation of the strategies outlined in the incident action plan, managing field operations, and thus ensuring that all physical resources and personnel are coordinated effectively.

While the operations section chief executes the strategy laid out in the incident action plan and manages ongoing field activities, the responsibility for determining incident objectives and strategies typically falls to the incident commander or a higher-level position within the command structure. This distinction underscores the collaborative nature of emergency response, where strategic decisions are made at a different level from the operational execution of those strategies. Therefore, the option regarding the operations section chief determining incident objectives and strategies is accurately identified as not part of their responsibilities.
