Where an officer-in-charge (OIC) of the rank of lieutenant is required, this is triggered when how many deputies are staffed at an extra duty assignment?

• A. 3 or more
• B. 4 or more
• C. 5 or more
• D. 6 or more

Answer: (B)

Supervision level for extra duty assignments is based on how many deputies are on the detail. When four or more deputies are staffed, an officer-in-charge at the lieutenant rank is required to oversee the operation. The lieutenant brings broader oversight, coordinates multiple teams, and maintains accountability, safety, and policy compliance across the detail. With smaller details (fewer staff), a sergeant or another capable supervisor typically handles the assignment; the larger the crew, the higher the level of supervision needed. So the four-or-more threshold is used to ensure proper command and control as the detail grows.
