Step-by-step explanation:
The Operations Section Chief would present information during the Operational Period Briefing in the Incident Command System (ICS). The Operational Period Briefing is designed to give an overview of the plan for the next operational period, including objectives, strategies, and resources needed. The Incident Commander may be present and have a role in the briefing, but it is the Operations Section Chief who typically conducts the briefing and goes into detail about the operational aspects. Other key personnel such as the Public Information Officer, Safety Officer, and other section chiefs would also attend the briefing to provide updates and information related to their respective areas.
