What should you do when taking a case during duty?

When handling a case during duty, the most appropriate action is to contact sector. This is because the sector plays a critical role in coordinating resources, providing guidance, and ensuring that the response is aligned with operational protocols. The sector's involvement is essential to ensure that all necessary information is communicated effectively and that the situation is managed in compliance with established procedures.

Keeping the sector informed allows for a broader assessment of the situation, enables the request for additional support if needed, and ensures a unified response by all involved units. This step also ensures that the proper channels of communication are maintained throughout the event, which is vital for accountability and operational effectiveness.

Other actions, such as calling for backup, notifying the base, or documenting the event, are important as well but are typically secondary steps that would follow the initial contact with the sector to facilitate a well-coordinated response.
